Duncan Sands 1895e98ef3 Transform (X/Y)*Y into X if the division is exact. Instcombine already knows how ... to do this and more, but would only do it if X/Y had only one use. Spotted as the most common missed simplification in SPEC by my auto-simplifier, now that it knows about nuw/nsw/exact flags. This removes a bunch of multiplications from 447.dealII and 483.xalancbmk. It also removes a lot from tramp3d-v4, which results in much more inlining. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124560 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-30 18:03:50 +00:00
