Fix a nasty bug in LegalizeTypes (spotted in
CodeGen/PowerPC/illegal-element-type.ll): suppose
a node X is processed, and processing maps it to
a node Y. Then X continues to exist in the DAG,
but with no users. While processing some other
node, a new node may be created that happens to
be equal to X, and thus X will be reused rather
than a truly new node. This can cause X to
"magically reappear", and since it is in the
Processed state in will not be reprocessed, so
at the end of type legalization the illegal node
X can still be present. The solution is to replace
X with Y whenever X gets resurrected like this.

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

specify a different name to be printed than the one that goes into the

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
