cf50a5390c 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.

525a3a67c1 llvm-mc: Support reassignment of variables in one special case, when the 
variable has not yet been used in an expression. This allows us to support a few
cases that show up in real code (mostly because gcc generates it for Objective-C
on Darwin), without giving up a reasonable semantic model for assignment.

e9f0fb4179 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...

c918d6043b 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.

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.

12ce0de462 Added support for X86 instruction prefixes so llvm-mc can assemble them. The 
Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
Also added versions of the move string and store string instructions without the
repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.

82a5946939 Added another version of the X86 assembler matcher test case. 
This test case is different subset of the full auto generated test case, and a
larger subset that is in x86_32-bit.s (that set will encode correctly).  These
instructions can pass though llvm-mc as it were a logical cat(1) and then
reassemble to the same instruction.  It is useful as we bring up the parser and
matcher so we don't break things that currently work.

ace63127bc llvm-mc: Fix darwin .section parsing. It was skipping the section name and a ',' 
(and outputting a diagnostic pointing at the wrong place), all of which lead to
much confusion.

a3741fa28b 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.

c114ed711e Added Mac OS X assembler style conditional assembly. I may come back and see if 
I can clean this up a bit more and do way with the TheCondState and just use
the top element on the TheCondStack if not empty.  Also may tweak the code
around ParseConditionalAssemblyDirectives() to simplify the AsmParser code.

20927f26fc 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.

c09e411102 llvm-mc: A few more parsing / match tweaks. 
- Operands which are just a label should be parsed as immediates, not memory
   operands (from the assembler perspective).

 - Match a few more flavors of immediates.

 - Distinguish match functions for memory operands which don't take a segment
   register.

 - We match the .s for "hello world" now!

a027d222e1 llvm-mc: Match a few X86 instructions. 
- This is "experimental" code, I am feeling my way around and working out the
   best way to do things (and learning tblgen in the process). Comments welcome,
   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.

the parsing of the .dump and .load should be done in the assembly parser and

just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.
