instruction sequence and cannot ordinarily be simplified by DAGcombine
into the various target description files or SPUDAGToDAGISel.cpp.
This makes some 64-bit operations legal.
- Eliminate target-dependent ISD enums.
- Update tests.

- select_bits.ll now fully functional now that PR1993 is closed. It was
previously broken by refactoring in SPUInstrInfo.td and using multiclasses.
- Same for eqv.ll

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.

Fixed CellSPU's A-form (local store) address mode, so that all globals,
externals, constant pool and jump table symbols are now wrapped within
a SPUISD::AFormAddr pseudo-instruction. This now identifies all local
store memory addresses, although it requires a bit of legerdemain during
instruction selection to properly select loads to and stores from local
store, properly generating "LQA" instructions.
Also added mul_ops.ll test harness for exercising integer multiplication.
