llvm/test/Transforms/Inline/crash2.ll
Chris Lattner b61789d4dd add a DEBUG call so that -debug lists when CGSCCPM iterates.
Fix RefreshCallGraph to use CGN->replaceCallEdge instead of hand
rolling its own loop.  replaceCallEdge properly maintains the
reference counts of the nodes, fixing a crash exposed by the
iterative callgraph stuff.
