Chris Lattner 178f4bb62d make the asm matcher emitter reject instructions that have comments
in their asmstring.  Fix the two x86 "NOREX" instructions that have them.
If these comments are important, the instlowering stuff can print them.

Chris Lattner 4d9f157203 fix an encoding mismatch where "sal %eax, 1" was not using the short encoding
for shl.  Caught by inspection.

Kevin Enderby 5e7cb5fc27 Added the x86 instruction ud2b (2nd official undefined instruction).

Kevin Enderby 9ad2166899 Yet another tweak to X86 instructions to add ud2a as an alias to ud2
(still to add ud2b).

Kevin Enderby 20b021c970 Another tweak to X86 instructions to add the missing flex instruction (without
the wait prefix).

Kevin Enderby 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.

Kevin Enderby ba985d9dd5 Added some aliases to the fcomip and fucompi Intel instructions. So that llvm-mc
will accept versions that the darwin assembler allows.  Forms ending in "pi" and
forms without all the operands.

Andrew Trick edd006c1c3 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.

Kevin Enderby 49843c0162 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 .

Kevin Enderby 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.

Chris Lattner 13111b08fb Replace a gross hack (the MOV64ri_alt instruction) with a slightly less
gross hack (having the asmmatcher handle the alias).

Chris Lattner b44b202d66 add support for the prefetch/prefetchw instructions, move femms into
the right file.  The assembler supports all the 3dnow instructions now,
but not the "3dnowa" ones.

Chris Lattner 3a0a620c2e what the heck, add support for the rest of the 3dNow! binary operations.

Chris Lattner 45270db916 Implement support for the bizarre 3DNow! encoding (which is unlike anything
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

Chris Lattner 4756bbeba0 fix a regression introduced in r115243, in which the instruction
backing int_x86_ssse3_pshuf_w got removed.  This caused PR8280.
