Chris Lattner fedced7bc3 Fix a really subtle and obnoxious memory bug that caused issues with an
llvm-gcc4 boostrap.  Whenever a node is deleted by the dag combiner, it
*must* be returned by the visit function, or the dag combiner will not
know that the node has been processed (and will, e.g., send it to the
target dag combine xforms).
