b02fe64d8b Add an unwind_to field to basic blocks, making them Users instead of Values. 
This is the first checkin for PR1269, the new EH infrastructure.

cfd005f2ea Add MVT::is128BitVector and is64BitVector. Shrink 
unaligned load/store code using them.  Per review
of unaligned load/store vector patch.

cb72d92471 Add pass to promote sret. 
This pass transforms 

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal void @foo(%struct._Point* sret  %agg.result)

into

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal %struct._Point @foo()

This pass updates foo() clients appropriately to use
getresult instruction to extract return values.

This pass is not yet ready for prime time.

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.
