392dd2b35f Changed the encoding of X86 floating point stack operations where both operands 
are st(0).  These can be encoded using an opcode for storing in st(0) or using
an opcode for storing in st(i), where i can also be 0.  To allow testing with
the darwin assembler and get a matching binary the opcode for storing in st(0)
is now used.  To do this the same logical trick is use from the darwin assembler
in converting things like this:

fmul %st(0), %st

into this:

fmul %st(0)

by looking for the second operand being X86::ST0 for specific floating point
mnemonics then removing the second X86::ST0 operand.  This also has the add
benefit to allow things like:

fmul %st(1), %st

that llvm-mc did not assemble.

e335a71a56 MC/X86: Chris pointed that 'as' isn't consistent in accepting the long form of 
instructions which have no direct register usage.

Darwin 'as' accepts:
  add $0, (%rax)
but rejects
  mov $0, (%rax)
for example.

Given that, only accept suffix matches which match exactly one form. We still
need to emit nice diagnostics for failures...

648d1ae783 MC/X86: Add "support" for matching ATT style mnemonic prefixes. 
- The idea is that when a match fails, we just try to match each of +'b', +'w',
   +'l'. If exactly one matches, we assume this is a mnemonic prefix and accept
   it. If all match, we assume it is width generic, and take the 'l' form.

 - This would be a horrible hack, if it weren't so simple. Therefore it is an
   elegant solution! Chris gets the credit for this particular elegant
   solution. :)

 - Next step to making this more robust is to have the X86 matcher generate the
   mnemonic prefix information. Ideally we would also compute up-front exactly
   which mnemonic to attempt to match, but this may require more custom code in
   the matcher than is really worth it.

c1eeb061e7 Fixed the encoding of the x86 push instructions. Using a 32-bit immediate value 
caused the a pushl instruction to be incorrectly encoding using only two bytes
of immediate, causing the following 2 instruction bytes to be part of the 32-bit
immediate value.  Also fixed the one byte form of push to be used when the
immediate would fit in a signed extended byte.  Lastly changed the names to not
include the 32 of PUSH32 since they actually push the size of the stack pointer.

8d8cb5c491 Fixed the SS42AI template for the SSE 4.2 instructions with TA prefix so it does 
not get an "Unknown immediate size" assert failure when used.  All instructions 
of this form have an 8-bit immediate.  Also added a test case of an example
instruction that is of this form.

766909ae3b Fixed the encoding problems of the crc32 instructions. All had the Operand size 
override prefix and only the r/m16 forms should have had that.  Also for variant
one, the AT&T syntax, added suffixes to all forms.  Also added the missing
64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.

1a50b05aff X86MCCodeEmitter: Fix two minor issues with reloc_riprel_4byte_movq_load, we 
were missing it on some movq instructions and were not including the appropriate
PCrel bias.

ab14df376a MC/X86/AsmMatcher: Use the new instruction cleanup routine to implement a 
temporary workaround for matching inc/dec on x86_64 to the correct instruction.
 - This hack will eventually be replaced with a robust mechanism for handling
   matching instructions based on the available target features.

files that produce special relocation types where the 
linker changes movq's into lea's.
