Somehow I was getting reasonable results for the test cases I was interested in despite not ever incrementing any path costs, so that the only nonzero costs arose from the all-left path in the first column. Anyway. Perform the diff starting from the beginning of the block to avoid capturing (say) loads of allocas. Vastly improves diff results on code that hasn't been mem2reg'ed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109741 91177308-0d34-0410-b5e6-96231b3b80d8
