David Green 4511f3fa86 [SCEV] Ensure that isHighCostExpansion takes into account what is being divided ... A SCEV is not low-cost just because you can divide it by a power of 2. We need to also check what we are dividing to make sure it too is not a high-code expansion. This helps to not expand the exit value of certain loops, helping not to bloat the code. The change in no-iv-rewrite.ll is reverting back to what it was testing before rL194116, and looks a lot like the other tests in replace-loop-exit-folds.ll.
