4bafa71dc1 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.

7f16ca4872 Make it simplier to dump DAGs while in DAGCombiner. Remove a nasty optimization.

25ad62d132 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.

9b1878a28c Fix a bug where we incorrectly turned '(X & 0) == 0' into '(X & 0) >> -1', 
which is undefined.  "0" isn't a power of 2.

6e08e7035f Eliminate SelectNodeTo() and getTargetNode() variants which take more than 
3 SDOperand operands. They are replaced by versions which take an array
of SDOperand and the number of operands.

8e8d9a3358 Add a new getNode() method that takes a pointer to an already-intern'd list 
of value-type nodes.  This avoids having to do mallocs for std::vectors of
valuetypes when a node returns more than one type.

kimwitu, but seems like a good idea from a "avoid performance cliffs" standpoint :)
