MFC r269393, r269394, r269395:

Fix parsing of arch extensions in binutils/gas.
Use ".arch_extension sec" when compiling ARM TI code that uses the
security extensions.

MFC r256790:

Fix the VCVT instruction. It must round towards zero when converting from
a floating-point to an integer value. This was not the case causing issues
when printing certain values.

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

Silence a warning that is incorrect on ARMv6 and later. In the smull, umull,
smlal, and umlal the output registers are allowed to be the same as either
input registers, where in ARMv4 and ARMv5 they could only be the same as the
last input register.

do_vfp_vmrs and do_vfp_vmsr should not return anything.

Add support for the vmsr and vmrs instructions. This supports the system
level version of the instructions. When used in userland the hardware only
allows us to read/write FPSCR.

Some ARM vmov similar to 'vmov.f32 s1, s2' will incorrectly have the second
register added to the symbol table by the assembler. On further
investigation it was found the problem was with the my_get_expression
function. This is called by parse_big_immediate.

Fix this by moving the call to parse_big_immediate to the end of the if,
else if, ..., else block.

Clear the memory allocated to build the unwind tables. This fixes C++
exceptions on ARM EABI with static binaries.

Recognise vfpv2 as a value for the ARM .fpu asm directive. Clang generates
these even when building soft floating-point code

Merging of projects/armv6, part 3

r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

Make GNU as recognize the ARM 'rrx' mnemonic, which can be generated by
clang for certain expressions. Code taken from Apple cctools (GPLv2).

Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things. Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.
