Duncan P. N. Exon Smith 27a3b015ef Revert part of "Cleanup some GraphTraits iteration code" ... This reverts part of r300656, which caused a regression in propagateMassToSuccessors by counting edges n^2 times, where n is the number of edges from the source basic block to the same successor basic block. The result was both incorrect and very slow to compute for large values of n (e.g. switches with multiple cases that go to the same basic block). Patch by Andrew Scheidecker! llvm-svn: 320208		2017-12-08 22:42:43 +00:00
