Two more Windows-related fixes:
...
- More enum signeness bitfield fixes (MSVC treats enums as signed).
- Fixed in Lex/HeaderSearch.cpp an unsafe copy between two
HeaderSearch::PerFileInfo entries in a common vector. The copy involved two
calls to getFileInfo() within the assignment; these calls could have
side-effects that enlarged the internal vector, and with MSVC this would
invalidate one of the values in the assignment.

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.

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.
