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.

53cca8590c eliminate the "MBBLabel" MCOperand type, and just use a MCSymbol for
MBB labels like everything else.

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.

fe33b51da0 remove the "old" at&t style asmprinter. Unfortunately, most of the
operand printing crapola cannot be removed yet because it is used by
the inline asm print stuff.

149ac38d37 Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't
working. To support this, add an is_displayed() function to raw_ostream,
and generalize Process::StandardOutIsDisplayed and friends in order to
support it.

Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.

While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.

6fb64b1b17 Fix PR4948 (and a leak): by not destroying the DwarfException
object, the timer it creates was not being deleted.  Since the
timer belonged to a static timer group, the timer group would
be destroyed on shutdown, and would notice and complain that
not all timers it contained were destroyed.

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.

36550f7606 add a new Mangler::getNameWithPrefix API which returns the
(uniqued if unnamed) global variable name with the prefix that
it is supposed to get.  It doesn't do "mangling" in the sense of
adding quotes and hacking on bad characters.

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.

aa66e3d968 Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and
how to fold notionally-out-of-bounds array getelementptr indices instead
of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
be done in a fairly general way without TargetData, and because not all
constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
more constant folding.

Also, set the "inbounds" flag when the getelementptr indices are
one-past-the-end.

58a0550024 Factor out the code for checking that all indices in a getelementptr are
within the notional bounds of the static type of the getelementptr (which
is not the same as "inbounds") from GlobalOpt into a utility routine,
and use it in ConstantFold.cpp to check whether there are any mis-behaved
indices.

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.
