3c9ab92a24 llvm-mc: Fix bugs where bytes were unintentionally being printed as signed.
- We now print all of 403.gcc cleanly (llvm-mc -> 'as' as diffed to 'as'), minus two 
   'rep;movsl' instructions (which I missed before).

b9d9ce9513 llvm-mc: When handling a .set, make sure to print subsequent references to the
symbol as the symbol name itself, not the expression it was defined to. These
have different semantics due to the quirky .set behavior (which absolutizes an
expression that would otherwise be treated as a relocation).

dc5840c57c Update llvm-mc / MCAsmStreamer to print the instruction using the actual target
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

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

677e05c42d 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.

9e2c3aa666 sink the 'name' and 'isdirective' state out of MCSection into its derived classes.
This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

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.

dd20299f97 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.

b66377bda2 Disable X86 AsmMatcher for now, it is causing gcc-4.0 to run out of memory on
i386-apple-darwin9. This presumably will get fixed once the generated code
improves.

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.

99d279978e 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!

41639473ed 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.

f1c0daa6a7 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
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.
