1a9158c301 MC: Add TargetAsmBackend::createObjectWriter. 
- MCAssembler is now object-file independent, although we will surely need more work to fully support ELF/COFF.

034843ac8b MC/Mach-O: Add isScatteredFixupFullyResolved, which implements the correct algorithm (used on x86_64) for determining whether an evaluated fixup is fully resolved (doesn't need relocation). 
- Test cases will follow, once we have x86_64 relocation support.

4e815f8a8c MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr. 
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

c28cc093e3 fix a memory leak yjasskin pointed out: MCSymbol is bump pointer 
allocated and thus not freed.  This is cool except that it contains
and std::string so the string data didn't get freed.  In any case
there is no reason to redundantly store the string data in the 
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.

f08fde41f3 MC/Mach-O: Implement initial support for relaxation. 
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)

d74acb0c78 This is a patch to the assembler frontend to detect when aligning a text 
section with TextAlignFillValue and calls EmitCodeAlignment() instead of
calling EmitValueToAlignment().  This allows x86 assembly code to be aligned
with optimal nops.

76687083a5 This is the second patch to allow x86 code to be aligned with optimal nops. 
With the compiler changed to use EmitCodeAlignment() it does change the
functionality.  But X86 assembly code assembled with llvm-mc does not change
its output.  For that we will eventually change the assembler frontend to
detect a '.align x, 0x90' when used in a section that 'hasInstructions' and use
EmitCodeAlignment, but will wait until we have better target hooks.

6e72048add This is the first patch to put the needed bits in place to eventually allow code 
to be aligned with optimal nops.  This patch does not change any functionality
and when the compiler is changed to use EmitCodeAlignment() it should also not
change the resulting output.  Once the compiler change is made and everything
looks good the next patch with the table of optimal X86 nops will be added to
WriteNopData() changing the output.  There are many FIXMEs in this patch which
will be removed when we have better target hooks (coming soon I hear).

8c6ed05157 Big change #1 for personality function references: 
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new 
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another 
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
-      O << "-" << MAI->getPCSymbol();

959fd88334 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).

3f6a960f9c llvm-mc/Mach-O: Add support for relocations. 
- I haven't really tried to find the "right" way to store the fixups or apply
   them, yet. This works, but isn't particularly elegant or fast.

 - Still no evaluation support, so we don't actually ever not turn a fixup into
   a relocation entry.

b9e7689c89 Add a target asm info hook to specify that particular bits of data in the FDE 
should be forced to 32-bits (.long) even on 64-bit architectures. Darwin wants
these bits to be 64-bits (.quad). However, other platforms may disagree.

This is just the info right now and is part of a work-in-progress which needs
this. We'll add the actual *use* of this soon.

0c7761b3f9 llvm-mc/Mach-O: Preliminary support for indirect symbols. 
- The indirect table itself isn't being filled in yet.

 - This isn't factored properly and is rather FIXMEd, but at the moment I'm more
   focused on figuring out what it needs to do.

6aff2fbd56 llvm-mc/Mach-O: Support symbol attributes. 
- This is mostly complete, the main thing missing is .indirect_symbol support
   (which would be straight-forward, except that the way it is implemented in
   'as' makes getting an exact .o match interesting).
