13354d7bbc implement support for 32-bit address operands in 64-bit mode, which 
are defined to emit the 0x67 prefix byte.  rdar://8482675

c14d59589c add basic avx support to the disassembler, also teach it about ssmem/sdmem 
operands.

With this done, we can remove the _Int suffixes from the round instructions
without the disassembler blowing up.  This allows the assembler to support
them, implementing rdar://8456376 - llvm-mc rejects 'roundss'

5cadf79b60 Fix rdar://8468087 - llvm-mc commutes fmul (and friend) operands. 
My previous fix for rdar://8456371 should only apply to fmulp/faddp,
not to fmul/fadd.  Instruction set orthogonality is overrated or 
something.

Daniel Dunbar
702c4ef9d8 MC/AsmParser: Support .single and .double for embedding floating point literals. 
- I believe more modern 'gas' supports a more enhanced set of arithmetic on
   them, but for now the only thing we can do is emit them as data.

1864d6728d 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.

a43c86b354 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the 
expression to include the modifier.
 - Gross, but this a corner case we don't expect to see often in practice, but
   it is worth accepting.
 - Also improves diagnostics on invalid modifiers.

1dd74c37c5 X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same 
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

3b0ff3bac3 MC/X86: We now match instructions like "incl %eax" correctly for the arch we are 
assembling; remove crufty custom cleanup code.
