Fix ScalarEvolution's "exhaustive" trip count evaluation code to avoid assuming that loops are in canonical form, as ScalarEvolution doesn't depend on LoopSimplify itself. Also, with indirectbr not all loops can be simplified. This fixes PR7416. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106389 91177308-0d34-0410-b5e6-96231b3b80d8
