4a33f01892 Change MCAsmStreamer to take an MCInstPrinter instead of a 
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

fb0e41caef make intel asmprinter use TRI::getAsmName instead of TRI::getName like 
all the other targets.  Add support for weak/linkonce linkage so it doesn't
crash on basically all nontrivial testcases.

96e22d6462 split MCInst printing out of the X86ATTInstPrinter 
class into its own X86ATTInstPrinter class.  The inst
printer now has just one dependence on the code generator
(TRI).

dfc3079a9e merge the linux cpool/jtbl pic tests into pic.ll and convert to filecheck. 
Change the picbase symbol on non-darwin systems from ".Lllvm$4.$piclabel" to
".L4$pb".  The actual name doesn't matter and the darwin name is shorter.

cbcbedf254 replace printBasicBlockLabel with EmitBasicBlockStart, 
now that printBasicBlockLabel is only used for starting
a MBB.  This allows elimination of a bunch of arguments.

ff9d0f20fa devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden. 
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that
we only have one place that decides what to name bb labels.  Hopefully various
clients of printBasicBlockLabel can start using GetMBBSymbol instead.

b2fdae122a X86MCInstLower::Lower should only not emit anything to OutStreamer, 
this means that it can only lower one MachineInstr to one MCInst.  To
make this fly, we need to pull out handling of MO_GOT_ABSOLUTE_ADDRESS
(which generates an implicit label) out of X86MCInstLower.

fb113da948 split MachineInstr -> MCInst lowering into its own class (not 
being embedded into X86ATTAsmPrinter).  This still depends heavily
on X86ATTAsmPrinter, but this is a step in the right direction.

operand printing crapola cannot be removed yet because it is used by
the inline asm print stuff.

316cce5a0f 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.

0f5802b4d8 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.

b9aca1a178 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.

52651f7623 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.

0b34068b2b 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.
