3676e24b67 Start the support for AVX instructions with 256-bit %ymm registers. A couple of 
notes:
- The instructions are being added with dummy placeholder patterns using some 256
  specifiers, this is not meant to work now, but since there are some multiclasses
  generic enough to accept them,  when we go for codegen, the stuff will be already
  there.
- Add VEX encoding bits to support YMM
- Add MOVUPS and MOVAPS in the first round
- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
- All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
  file.

012d7537ee Rework segment prefix emission code to handle segments 
in memory operands at the same type as hard coded segments.
This fixes problems where we'd emit the segment override after
the REX prefix on instructions like:
mov %gs:(%rdi), %rax

This fixes rdar://8127102.  I have several cleanup patches coming
next.

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.

parses the .word directive as 4 bytes and ARMAsmParser::ParseInstruction will
give an error is called.  Broke out the test of the .word directive into two
different test cases, one for x86 and one for arm.

dc5840c57c Update llvm-mc / MCAsmStreamer to print the instruction using the actual target

 - This makes it possible to do some correctness checking of the parsing and

   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

07d36a8194 llvm-mc/AsmMatcher: Improve match code. 
- This doesn't actually improve the algorithm (its still linear), but the
   generated (match) code is now fairly compact and table driven. Still need a
   generic string matcher.

 - The table still needs to be compressed, this is quite simple to do and should
   shrink it to under 16k.

 - This also simplifies and restructures the code to make the match classes more
   explicit, in anticipation of resolving ambiguities.

88ccb58384 llvm-mc/AsmMatcher: Move to a slightly more sane matching design. 
- Still not very sane, but a least its not 60k lines on X86. :)

 - In terms of correctness, currently some things are hard wired for X86, and we
   still don't properly resolve ambiguities (this is ignoring the instructions
   we don't even match due to funny .td stuff or other corner cases).

The high level changes:
 1. Represent tokens which are significant for matching explicitly as separate
    operands. This uniformly handles not only the instruction mnemonic, but
    also 'signficiant' syntax like the '*' in "call * ...".

 2. Separate the matching of operands to an instruction from the construction of
    the MCInst. In theory this can be done during matching, but since the number
    of variations is small I think it makes sense to decompose the problems.

 3. Improved a few of the mechanisms to at least successfully flatten / tokenize
    the assembly strings for PowerPC and ARM.

 4. The comment at the top of AsmMatcherEmitter.cpp explains the approach I'm
    moving towards for handling ambiguous instructions. The high-bit is to infer
    a partial ordering of the operand classes (and force the user to specify one
    if we can't) and use that to resolve ambiguities.

- This is "experimental" code, I am feeling my way around and working out the

   but keep in mind this stuff will change radically.

 - This is enough to match "subb" and friends, but not much else. The next step is to
   automatically generate the matchers for individual operands.
