907355caf8 On x86-64, the 32-bit cmov doesn't actually clear the high 32-bit of 
its result if the condition is false.

90edac0e8b 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.

4c66f729c9 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.

7cb384dcca 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.

e9434dbff4 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.

on X86ATTAsmPrinter, but this is a step in the right direction.
