Duncan Sands d0c6f3dafd Factor code for testing whether replacing one value with another ... preserves LCSSA form out of ScalarEvolution and into the LoopInfo class. Use it to check that SimplifyInstruction simplifications are not breaking LCSSA form. Fixes PR8622. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119727 91177308-0d34-0410-b5e6-96231b3b80d8		2010-11-18 19:59:41 +00:00
