Reverting r117031 to cleanup valgrind errors.
...
It doesn't look like anything is wrong with the checkin,
but the new test cases expose a mem bug in AsmParser.

More 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. Also added the missing flex (without the wait prefix)
and ud2a as an alias to ud2 (still to add ud2b).

Added a few tweaks to the Intel Descriptor-table support instructions to allow
...
word forms and suffixed versions to match the darwin assembler in 32-bit and
64-bit modes. This is again for use just with assembly source for llvm-mc .
