Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate
...
their operands with the node itself. This reduces malloc traffic for operand
lists. This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.

For PR786:
...
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

When SimplifySetCC was moved to the DAGCombiner, it was never removed from
...
SelectionDAG and it has since bitrotted. Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.
This fixes obscure bugs.
