6a715dccdf llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported for now. 
- Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency).

4d7b2e3307 llvm-mc/Mach-O: Unique sections properly, so we don't get duplicate text 
sections, etc.
 - The quick and dirty way, just clone the TargetLoweringObjectFile
   code. Eventually this should be shared... somehow.

e73b267301 llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table. 
- I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).

6860ac7375 llvm-mc: Clean up some handling of symbol/section association to be more correct 
(external was really undefined and there wasn't an explicit representation for
absolute symbols).
 - This still needs some cleanup to how the absolute "pseudo" section is dealt
   with, but I haven't figured out the nicest approach yet.

67dfb1de23 llvm-mc: Improve handling of implicit alignment for magic section directives 
(e.g., .objc_message_refs).
 - Just emit a .align when we see the directive; this isn't exactly what 'as'
   does but in practice it should be ok, at least for now. See FIXME.

4abcccb965 llvm-mc: In a .fill directive, still honor .align even if invalid maximum bytes 
count is given (this matches 'as').

9df5f33818 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.

9af747b421 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.

cb307a27bf 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?

591105c540 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!! ;-)

089b7de20d switch this to create coff sections for now, it doesn't really matter for 
llvm-mc's purpose yet and we'll want to switch to creating semantic sections
at some point.

d9f952948e 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.

ee5513582d 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.
