MFC r262613:

Merge the projects/clang-sparc64 branch back to head. This brings in
several updates from the llvm and clang trunks to make the sparc64
backend fully functional.

Apart from one patch to sys/sparc64/include/pcpu.h which is still under
discussion, this makes it possible to let clang fully build world and
kernel for sparc64.

Any assistance with testing this on actual sparc64 hardware is greatly
appreciated, as there will unavoidably be bugs left.

Many thanks go to Roman Divacky for his upstream work on getting the
sparc64 backend into shape.

MFC r262985:

Repair a few minor mismerges from r262261 in the clang-sparc64 project
branch. This is also to minimize differences with upstream.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Fix a comment in an asm block to work with compilers other than GCC

Revert part of r211505. Some of the removed casts are actually safe so
put them back in again. Also, clang only complained about the lvalue
cast.

Pointed out: bde

Remove unneeded casts in inline assembly in contrib/gcc/longlong.h,
which are apparently "heinous" GNU extensions, so clang can
compile this without using the -fheinous-gnu-extensions option.

Results in *no* binary change, neither with clang, nor with gcc.

Virgin import of the GCC 2.95.1 compilers

Virgin import of gcc from EGCS 1.1.2

Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the
non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.
