feec7137ce Switch SelectionDAG::ReplaceAllUsesOfValueWith to use a SmallSetVector for 
the users set (most nodes have 1 or 2 users).  This speeds up the isel pass
3.2% on kimwitu.

de46e48420 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.

e7d2c24a7d Make it simplier to dump DAGs while in DAGCombiner. Remove a nasty optimization.

bd9acad805 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.
