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.

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.

c3ef5b0802 Follow up to 81494. When the folded reload is narrowed to a 32-bit load then change the destination register to a 32-bit one or add a sub-register index.

93831c07de It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not 
safe. This can happen we a subreg_to_reg 0 has been coalesced. One
exception is when the instruction that folds the load is a move, then we
can simply turn it into a 32-bit load from the stack slot.

9f0fb453d8 Added the ParseInstruction() hook for target specific assembler directives so 
that things like .word can be parsed as target specific.  Moved parsing .word
out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes
for other targets that support the .word directive.

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.
