Tweaks to X86 instructions to allow the 'w' suffix in places it makes
sense, when the instruction takes the 16-bit ax register or m16 memory
location. These changes to llvm-mc matches what the darwin assembler
allows for these instructions. Done differently than in r117031 that
caused a valgrind error which was later reverted.
