b897e807c4 llvm-mc: Simplify EmitAssignment ('.set' is identical to '=').

fcb32716eb llvm-mc: Switch MCInst to storing an MCExpr* instead of an MCValue. 
Also, use MCInst::print instead of custom code in MCAsmPrinter.

053a5f22a0 llvm-mc: Switch MCExpr construction to using static member functions, and taking the MCContext (which now owns all MCExprs).

bc61205626 llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported for now. 
- Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency).

e3cf39c644 llvm-mc: .lsym is more unsupported than unimplemented, pending a use case appearing. 
Also, all one of the file level flags are implemented.

5749caa698 llvm-mc: Support .zerofill emission. 
- I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences.

1f70368155 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).

8c38017009 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.

Also, simplify some of Mach-O writer code which can now use section addresses.

a6284af6bb Revert last patch. We need to put this into TargetLowering. There will be a lot 
of EH stuff going into there, so we can wait to add them all then.

4dd702ce66 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.

344ea15334 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.

937b745b68 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).

39262eb119 prune the #includes in raw_ostream.h by moving a 
member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

4c3cf93d1d llvm-mc/Mach-O: Improve symbol table support: 
- Honor .globl.

 - Set symbol type and section correctly ('nm' now works), and order symbols
   appropriately.

 - Take care to the string table so that the .o matches 'as' exactly (for ease
   of testing).

d22c0d4d49 llvm-mc/Mach-O: Sketch symbol table support. 
- The only .s syntax this honors right now is emitting labels, and some parts
   of the symbol table generation are wrong or faked.

 - This is enough to get nm to report such symbols... incorrectly, but still.

Also, fixed byte emission to extend the previous fragment if possible.
