295ae42ede Don't track max alignment during stack object allocations since they can be deleted later. Let PEI compute it.

689d8cac04 Convert SimplifyDemandedMask and ShrinkDemandedConstant to use APInt. 
Change several cases in SimplifyDemandedMask that don't ever do any
simplifying to reuse the logic in ComputeMaskedBits instead of
duplicating it.

a369a6add8 Some platforms use the same name for 32-bit and 64-bit registers (like 
%r3 on PPC) in their ASM files. However, it's hard for humans to read
during debugging. Adding a new field to the register data that lets you
specify a different name to be printed than the one that goes into the
ASM file -- %x3 instead of %r3, for instance.

36bbc39272 Merge current work back to tree to minimize diffs and drift. Major highlights 
for CellSPU modifications:

- SPUInstrInfo.td refactoring: "multiclass" really is _your_ friend.
- Other improvements based on refactoring effort in SPUISelLowering.cpp,
  esp. in SPUISelLowering::PerformDAGCombine(), where zero amount shifts and
  rotates are now eliminiated, other scalar-to-vector-to-scalar silliness
  is also eliminated.
- 64-bit operations are being implemented, _muldi3.c gcc runtime now
  compiles and generates the right code. More work still needs to be done.
