Reland "Fix miscompile of MS inline assembly with stack realignment"

The tests have been fixed to pass on platforms with a stack alignment larger than 4.
Update to clang side tests will land shortly.
Pull in r196986 from upstream llvm trunk (by Reid Kleckner):
Revert the backend fatal error from r196939
The combination of inline asm, stack realignment, and dynamic allocas turns out to be too common to reject out of hand.
ASan inserts empy inline asm fragments and uses aligned allocas. Compiling any trivial function containing a dynamic alloca with ASan is enough to trigger the check.
XFAIL the test cases that would be miscompiled and add one that uses the relevant functionality.
Pull in r202930 from upstream llvm trunk (by Hans Wennborg):
Check for dynamic allocas and inline asm that clobbers sp before building selection dag (PR19012)
In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo to make sure that ESI isn't used as a base pointer register before we choose to emit rep movs (which clobbers esi).
The problem is that MachineFrameInfo wouldn't know about dynamic allocas or inline asm that clobbers the stack pointer until SelectionDAGBuilder has encountered them.
This patch fixes the problem by checking for such things when building the FunctionLoweringInfo.
Differential Revision: http://llvm-reviews.chandlerc.com/D2954
Together, these commits fix the problem encountered in the devel/emacs port on the i386 architecture, where a combination of stack realignment, alloca() and memcpy() could incidentally clobber the %esi register, leading to segfaults in the temacs build-time utility.

ISel: Make VSELECT selection terminate in cases where the condition type has to be split and the result type widened.
When the condition of a vselect has to be split it makes no sense widening the vselect and thereby widening the condition. We end up in an endless loop of widening (vselect result type) and splitting (condition mask type) doing this. Instead, split both the condition and the vselect and widen the result.
I ran this over the test suite with i686 and mattr=+sse and saw no regressions.

Pull in r196874 from upstream llvm trunk:
Fix a crash that occurs when PWD is invalid.
MCJIT needs to be able to run in hostile environments, even when PWD is invalid. There's no need to crash MCJIT in this case.
The obvious fix is to simply leave MCContext's CompilationDir empty when PWD can't be determined. This way, MCJIT clients, and other clients that link with LLVM don't need a valid working directory.
If we do want to guarantee valid CompilationDir, that should be done only for clients of getCompilationDir(). This is as simple as checking for an empty string.
The only current use of getCompilationDir is EmitGenDwarfInfo, which won't conceivably run with an invalid working dir. However, in the purely hypothetically and untestable case that this happens, the AT_comp_dir will be omitted from the compilation_unit DIE.
This should help fix assertions occurring with ports-mgmt/tinderbox, when it is using jails, and sometimes invalidates clang's current working directory.

ISelDAG: spot chain cycles involving MachineNodes
Previously, the DAGISel function WalkChainUsers was spotting that it had entered already-selected territory by whether a node was a MachineNode (amongst other things). Since it's fairly common practice to insert MachineNodes during ISelLowering, this was not the correct check.
Looking around, it seems that other nodes get their NodeId set to -1 upon selection, so this makes sure the same thing happens to all MachineNodes and uses that characteristic to determine whether we should stop looking for a loop during selection.

Stop using the ISD::EXCEPTIONADDR and ISD::EHSELECTION when lowering landing pad arguments. These nodes were previously legalized into CopyFromReg nodes, but that never worked properly because the CopyFromReg node weren't guaranteed to be scheduled at the top of the basic block.
This meant the exception pointer and selector registers could be clobbered before being copied to a virtual register.
This patch copies the two physical registers to virtual registers at the beginning of the basic block, and lowers the landingpad instruction directly to two CopyFromReg nodes reading the *virtual* registers. This is safe because virtual registers don't get clobbered.
A future patch will remove the ISD::EXCEPTIONADDR and ISD::EHSELECTION nodes.

MFC r251216 (by ed): Pull in r183033 and r183036 from LLVM trunk:
Add support for optimized (non-generic) atomic libcalls.
For integer types of sizes 1, 2, 4 and 8, libcompiler-rt (and libgcc) provide atomic functions that pass parameters by value and return results directly.
libgcc and libcompiler-rt only provide optimized libcalls for __atomic_fetch_*, as generic libcalls on non-integer types would make little sense. This means that we can finally make __atomic_fetch_* work on architectures for which we don't provide these operations as builtins (e.g. ARM).
This should fix the dreaded "cannot compile this atomic library call yet" error that would pop up once every while.
This should make it possible for me to get C11 atomics working on all of our platforms.

MFC r251761: Pull in r181620 from llvm trunk:
[ms-inline asm] Fix a crasher when we fail on a direct match.
The issue was that the MatchingInlineAsm and VariantID args to the MatchInstructionImpl function weren't being set properly. Specifically, when parsing intel syntax, the parser thought it was parsing inline assembly in the at&t dialect; that will never be the case.
The crash was caused when the emitter tried to emit the instruction, but the operands weren't set. When parsing inline assembly we only set the opcode, not the operands, which is used to lookup the instruction descriptor. rdar://13854391 and PR15945
Also, this commit reverts r176036. Now that we're correctly parsing the intel syntax the pushad/popad don't match properly. I've reimplemented that fix using a MnemonicAlias.

PR15662: Optimized debug info produces out of order function parameters
When a function is inlined we lazily construct the variables representing the function's parameters. After that, we add any remaining unused parameters.
If the function doesn't use all the parameters, or uses them out of order, then the DWARF would produce them in that order, producing a parameter order that doesn't match the source.
This fix causes us to always keep the arg variables at the start of the variable list & in the original order from the source.

Pull in r178240 from upstream llvm trunk:
Section 24.2.2 of the C++ standard, [iterator.iterators], Table 106 requires that the return type of *r for all iterators r be reference, where reference is defined in [iterator.requirements.general]/p11 as iterator_traits<X>::reference, and X is the type of r.
But in CFG.h, the dereference operator of PredIterator and SuccIterator return pointer, not reference.
Furthermore the nested type reference is value_type&, which is not the type returned from operator*().
This patch simply makes the iterator::reference type value_type*, which is what the operator*() returns, and then re-lables the return type as reference.
From a functionality point of view, the only difference is that the nested reference type is now value_type* instead of value_type&.
This enables building clang 3.2 with the newer version of libc++ that was merged in r250514 (and which has stricter iterator requirements for the vector member templates).

[C++11 Compat] Fix breaking change in C++11 pair copyctor.
While this code is valid C++98, it is not valid C++11. The problem can be reduced to:
class MDNode;
class DIType { operator MDNode*() const {return 0;} };
class WeakVH { WeakVH(MDNode*) {} };
int main() { DIType di; std::pair<void*, WeakVH> p(std::make_pair((void*)0, di))); }
This was not detected by any of the bots we have because they either compile C++98 with libstdc++ (which allows it), or C++11 with libc++ (which incorrectly allows it). I ran into the problem when compiling with VS 2012 RC.
Thanks to Richard for explaining the issue.

Pull in r165367 from upstream llvm trunk:
Make sure always-inline functions get inlined. <rdar://problem/12423986>
Without this change, when the estimated cost for inlining a function with an "alwaysinline" attribute was lower than the inlining threshold, the getInlineCost function was returning that estimated cost rather than the special InlineCost::AlwaysInlineCost value. That is fine in the normal inlining case, but it can fail when the inliner considers the opportunity cost of inlining into an internal or linkonce-odr function. It may decide not to inline the always-inline function in that case. The fix here is just to make getInlineCost always return the special value for always-inline functions. I ran into this building clang with libc++. Tablegen failed to link because of an always-inline function that was not inlined. I have been unable to reduce the testcase down to a reasonable size.
This should fix the link errors that were reported when atf-run was compiled with clang -stdlib=libc++. In this case, at -O3 optimization, some calls to basic_ios::clear() were not inlined, even when the function was marked __always_inline__.

etire the cpumask_t type and replace it with cpuset_t usage.
This is intended to fix the bug where cpu mask objects are capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever value. Anyway, as long as several structures in the kernel are statically allocated and sized as MAXCPU, it is suggested to keep it as low as possible for the time being.
Technical notes on this commit itself: - More functions to handle with cpuset_t objects are introduced. The most notable are cpusetobj_ffs() (which calculates a ffs(3) for a cpuset_t object), cpusetobj_strprint() (which prepares a string representing a cpuset_t object) and cpusetobj_strscan() (which creates a valid cpuset_t starting from a string representation). - pc_cpumask and pc_other_cpus are target to be removed soon. With the moving from cpumask_t to cpuset_t they are now inefficient and not really useful. Anyway, for the time being, please note that access to pcpu datas is protected by sched_pin() in order to avoid migrating the CPU while reading more than one (possible) word - Please note that size of cpuset_t objects may differ between kernel and userland. While this is not directly related to the patch itself, it is good to understand that concept and possibly use the patch as a reference on how to deal with cpuset_t objects in userland, when accessing kernland members. - KTR_CPUMASK is changed and now is represented through a string, to be set as the example reported in NOTES.
Please additively note that no MAXCPU is bumped in this patch, but private testing has been done until to MAXCPU=128 on a real 8x8x2(htt) machine (amd64).
Please note that the FreeBSD version is not yet bumped because of the upcoming pcpu changes. However, note that this patch is not targeted for MFC.
People to thank for the time spent on this patch: - sbruno, pluknet and Nicholas Esborn (nick AT desert DOT net) tested several revision of the patches and really helped in improving stability of this work. - marius fixed several bugs in the sparc64 implementation and reviewed patches related to ktr. - jeff and jhb discussed the basic approach followed. - kib and marcel made targeted review on some specific part of the patch. - marius, art, nwhitehorn and andreast reviewed MD specific part of the patch. - marius, andreast, gonzo, nwhitehorn and jceel tested MD specific implementations of the patch. - Other people have made contributions on other patches that have been already committed and have been listed separately.
Companies that should be mentioned for having participated at several degrees: - Yahoo! for having offered the machines used for testing on big count of CPUs. - The FreeBSD Foundation for having sponsored my devsummit attendance, which has been instrumental. - Sandvine for having offered offices and infrastructure during development.
(I really hope I didn't forget anyone, if it happened I apologize in advance).

Make cross-compiling using clang work better, by respecting the LLVM_HOSTTRIPLE that is defined during the cross-tools stage.
Using clang, you can now build amd64 world and kernel on i386, and vice versa. Other arches still need work.

Update llvm/clang to trunk r126547.
There are several bugfixes in this update, but the most important one is to ensure __start_ and __stop_ symbols for linker sets and kernel module metadata are always emitted in object files:
http://llvm.org/bugs/show_bug.cgi?id=9292
Before this fix, if you compiled kernel modules with clang, they would not be properly processed by kldxref, and if they had any dependencies, the kernel would fail to load those. Another problem occurred when attempting to mount a tmpfs filesystem, which would result in 'operation not supported by device'.

Recently, in upstream clang, a fix was done to add -L/usr/lib to the arguments passed to ld, when linking. This was to appease configure scripts in several ports, that grep for such a -L option in "${CC} -v" output, to determine the startup objects passed to ld. Note ld itself does not need to be told about /usr/lib, since it has this path builtin anyway.
However, if clang is built as a bootstrap tool during buildworld, it should not use *anything* outside ${WORLDTMP} to include or link with. The upstream fix to add -L/usr/lib breaks this assumption, and can thus cause libraries from /usr/lib to be linked in during buildworld.
This can result in buildworld dying during linking of zinject, where it picks up the wrong copy of libzpool.so, eventually leading to:
/usr/obj/usr/src/tmp/lib/libthr.so.3: undefined reference to `_rtld_get_stack_prot'
Fix this issue by not adding any hardcoded paths, but by looping through the run-time library path list, which is already correctly set for the bootstrap phase.

Rework the analysis of the 'r' specifier. It turns out that we can't make it like xArg because they are different ('x' doesn't accept sign, but 'r' does). This fixes some warnings when building DDB with clang.

Upgrade our Clang in base to r108428.
This commit merges the latest LLVM sources from the vendor space. It also updates the build glue to match the new sources. Clang's version number is changed to match LLVM's, which means /usr/include/clang/2.0 has been renamed to /usr/include/clang/2.8.

Do the branding right this time.
I've looked at other places in the source tree where CLANG_VENDOR is used and I suspect it might not be safe to use newlines here. CLANG_VENDOR should just be defined to "FreeBSD ", just like the latest Clang preview in OS X uses "Apple ". Properly use SVN_REVISION to define it to the imported revision of Clang. I do want to have a date in there, so slightly modify the code to support CLANG_VENDOR_SUFFIX.
