Yet another tweak to X86 instructions to add ud2a as an alias to ud2

a1917c7555
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.

Reverting r117031 to cleanup valgrind errors.

It doesn't look like anything is wrong with the checkin,

64-bit modes. This is again for use just with assembly source for llvm-mc .

b9783dd9bc
Added a handful of x86-32 instructions that were missing so that llvm-mc would
...
be more complete. These are only expected to be used by llvm-mc with assembly
source so there is no pattern, [], in the .td files. Most are being added to
X86InstrInfo.td as Chris suggested and only comments about register uses are
added. Suggestions welcome on the .td changes as I'm not sure on every detail
of the x86 records. More missing instructions will be coming.

Fix an inconsistency in the x86 backend that led it to reject "calll foo" on
...
x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly
named "callq", so this only impacted x86-32.
This fixes rdar://8456370 - llvm-mc rejects 'calll'
This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.
