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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102120 91177308-0d34-0410-b5e6-96231b3b80d8
