2a3c20bf26 change FnStubs from being a StringMap<std::string> to being a much 
more efficient SmallPtrSet<MCSymbol*>.  This eliminates string
craziness and fixes CodeGen/X86/darwin-quote.ll with the new asmprinter.

Codegen is producing stubs in a nondeterminstic order, but it was doing
this before anyway.

a49ea86ba2 reimplement X86ATTAsmPrinter::GetGlobalAddressSymbol in terms of 
Mangler::getNameWithPrefix.  In addition to avoiding some over
quoting, this also is more efficient because it uses smallvector
instead of std::string thrashing.

c5ea263a23 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

65c060064d add a gross hack to get "SrcLine" comments to show up with the 
new asmprinter.  Differently gross hack coming next.

634cca377a hoist the call to processDebugLoc out of the generated 
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

printing stuff are quoting symbols now, breaking objc testcases.

d842962e27 change selectiondag to add the sign extended versions of immediate operands 
to instructions instead of zero extended ones.  This makes the asmprinter
print signed values more consistently.  This apparently only really affects
the X86 backend.

975d7e0392 Implement support for X86II::MO_GOT_ABSOLUTE_ADDRESS. We get very 
different formatting from the old asmprinter, but it should be 
semantically the same.  We used to get:

	popl	%eax
	addl	$_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$6.$piclabel], %eax
...

Now we get:

	popl	%eax
.Lpicbaseref6:
	addl	$(_GLOBAL_OFFSET_TABLE_ + (.Lpicbaseref6 - .Lllvm$6.$piclabel)), %eax
...
