Take the next steps in making SDUse more consistent with LLVM Use, and
...
tidy up SDUse and related code.
- Replace the operator= member functions with a set method, like
LLVM Use has, and variants setInitial and setNode, which take
care up updating use lists, like LLVM Use's does. This simplifies
code that calls these functions.
- getSDValue() is renamed to get(), as in LLVM Use, though most
places can either use the implicit conversion to SDValue or the
convenience functions instead.
- Fix some more node vs. value terminology issues.
Also, eliminate the one remaining use of SDOperandPtr, and
SDOperandPtr itself.

- Capitulate to the DAGCombiner and move i64 constant loads to instruction
selection (SPUISelDAGtoDAG.cpp).
<rant>DAGCombiner will insert all kinds of 64-bit optimizations after
operation legalization occurs and now we have to do most of the work that
instruction selection should be doing twice (once to determine if v2i64
build_vector can be handled by SelectCode(), which then runs all of the
predicates a second time to select the necessary instructions.) But,
CellSPU is a good citizen.</rant>
