Add a method to ScalarEvolution for telling it when a loop has been
modified in a way that may effect the trip count calculation. Change IndVars to use this method when it rewrites pointer or floating-point induction variables instead of using a doInitialization method to sneak these changes in before ScalarEvolution has a chance to see the loop. This eliminates the need for LoopPass to depend on ScalarEvolution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64810 91177308-0d34-0410-b5e6-96231b3b80d8
