Jakob Stoklund Olesen d489632f94 Allow for customized graph edge pruning in PostOrderIterator.h ... Make it possible to prune individual graph edges from a post-order traversal by specializing the po_iterator_storage template. Previously, it was only possible to prune full graph nodes. Edge pruning makes it possible to remove loop back-edges, for example. Also replace the existing DFSetTraits customization hook with a po_iterator_storage method for observing the post-order. DFSetTraits was only used by LoopIterator.h which now provides a po_iterator_storage specialization. Thanks to Sean and Chandler for reviewing. llvm-svn: 160366		2012-07-17 15:35:40 +00:00
