fb4a6b3976 llvm-mc: Start MCAssembler and MCMachOStreamer. 
- Together these form the (Mach-O) back end of the assembler.

 - MCAssembler is the actual assembler backend, which is designed to have a
   reasonable API. This will eventually grow to support multiple object file
   implementations, but for now its Mach-O/i386 only.

 - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API,
   e.g. converting the various directives into fragments, managing state like
   the current section, and so on.

 - llvm-mc will use the new backend via '-filetype=obj', which may eventually
   be, but is not yet, since I hear that people like assemblers which actually
   assemble.

 - The only thing that works at the moment is changing sections. For the time
   being I have a Python Mach-O dumping tool in test/scripts so this stuff can
   be easily tested, eventually I expect to replace this with a real LLVM tool.

 - More doxyments to come.

I assume that since this stuff doesn't touch any of the things which are part of
2.6 that it is ok to put this in not so long before the freeze, but if someone
objects let me know, I can pull it.

b3f3c0387b llvm-mc: Various section parsing fixes. 
- Add missing flags for various Objective-C sections.

 - Fix names for [non_]lazy_symbol_pointer (these are misspelled in the manual).

 - .symbol_stub does not have the self modifying code flag set (this appears to
   be wrong in the manual?).

 - Add implicit alignment values; not yet used.

Also, call MCStreamer::Finish at the end of a successful parse.

c22e0b2443 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. :)

ff4bc460c5 Make the big switch: Change MCSectionMachO to represent a section *semantically* 
instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?

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.

a5881e3060 Add TargetRegistry::lookupTarget. 
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

   just use lookahead, though.
