Daniel Berlin 77fa84eadd Correct IDF calculator for ReverseIDF ...

Summary:
Need to use predecessors for reverse graph, successors for forward graph.
succ_iterator/pred_iterator are not compatible, this patch is all the work necessary to work around that (which is what everywhere else does).  Not sure if there is a better way, so cc'ing some random folks to take a gander :)
