Terminator may have returned value, so we need to replace uses, and in general handle invoke as a branch inst. I'm not sure this is the best handling, but IMO poorly reduced input is much better than crashing reduction tool. A (previously-crashing!) test added. Fixes https://bugs.llvm.org/show_bug.cgi?id=46818
