Duncan Sands a0e08bf0d4 Since commit 157467, if reassociate isn't actually going to change an expression ... then it doesn't alter the instructions composing it, however it would continue to move the instructions to just before the expression root. Ensure it doesn't move them either, so now it really does nothing if there is nothing to do. That commit also ensured that nsw etc flags weren't cleared if the expression was not being changed. Tweak this a bit so that it doesn't clear flags on the initial part of a computation either if that part didn't change but later bits did. llvm-svn: 157518		2012-05-26 16:42:52 +00:00
