Make a new X8632_MachoTargetObjectFile TLOF implementation whose

needs to register the stub it references with MachineModuleInfoMachO,
so that it gets emitted at the end of the file.

Move stub emission from X86ATTAsmPrinter::doFinalization to the
new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook.  The important
thing here is that EmitEndOfAsmFile is called *after* the ehframes are
emitted, so we get all the stubs.

This allows us to remove a gross hack from the asmprinter where it would
"just know" that it needed to output stubs for personality functions.
Now this is all driven from a consistent interface.

The testcase change is just reordering the expected output now that the
stubs come out after the ehframe instead of before.

Fix a few places where PointerIntPair was using PointerLikeTypeTraits<PointerTy>
instead of the PtrTraits provided.  Allows PointerIntPair to contain a
PointerUnion safely, as long as the bits add up.

Fix PR4910: Broken logic in coalescer means when a physical register liveness is being shortened, the sub-registers were not. The symptom is the register allocator could not find a free register for this particular test.

Add a new pass for doing late hoisting of floating-point and vector
constants out of loops. These aren't covered by the regular LICM
pass, because in LLVM IR constants don't require separate
instructions. They're not always covered by the MachineLICM pass
either, because it doesn't know how to unfold folded constant-pool
loads. This is somewhat experimental at this point, and off by
default.
