Move the initialization of SEL/objc_selector from Sema::Sema() to Sema::ActOnTranslationUnitScope() and make sure the type/struct get inserted into the translation unit scope.

up BUILD_PAIR, though it didn't really have to.  Like
most of LegalizeTypes, does not support soft-float.
This cures all "make check" vector building failures.

- 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.

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.
