27e1fe9dab Corrected load folding check. We need to start from the root of the sub-dag
being matched and ensure there isn't a non-direct path to the load (i.e. a
path that goes out of the sub-dag.)

root of the matched sub-tree.

4c1984d9e8 testcase for recent dag combiner patch. Before the entry bb was:

after it is:

51dabfb283 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.
