Next round of DAGCombiner changes. This version now passes all the tests
...
I have run so far when run before Legalize. It still needs to pick up the
SetCC folds, and nodes that use SetCC.

Next round of DAG Combiner changes. Just need to support multiple return
...
values, and then we should be able to hook it up.

First pass at the DAG Combiner. It isn't used anywhere yet, but it should
...
be mostly functional. It currently has all folds from SelectionDAG.cpp
that do not involve a condition code.
