Instead of testing whether an instruction dominates the loop preheader, test whether it properly dominates the loop header. This is equivalent when the loop has a preheader, and has the advantage of working when the loop doesn't have a preheader. Since IVUsers doesn't Require LoopSimplify, the loop isn't guaranteed to have a preheader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82899 91177308-0d34-0410-b5e6-96231b3b80d8
