Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537

Move the re-sort of invalidated NonLocalPointerDeps cache earlier so that all code paths get it. PR4256 was about a case where the phi translation loop would find all preds in the Visited cache, so it could get by without re-sorting the NonLocalPointerDeps cache. Fix this by resorting it earlier, there is no reason not to do this. This patch inspired by Jakub Staszak's patch. llvm-svn: 75476
