This looks useful as a separate function, the interface looks pretty clean and I think it lives nicely in LoopUtils.

+                                             ReplaceExitValue, DeadInsts)) {
+      NumReplaced = Rewrites;
+      Changed |= NumReplaced;
----------------
NumReplaced += Rewrites; maybe?
