Now that we use an ilist of machine instructions, iterators are more robust than before. Because this is the case, we can compute the first non-phi instruction once when de-phi'ing a block. This shaves ~4s off of phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s. There are still much more important gains to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13452 91177308-0d34-0410-b5e6-96231b3b80d8
