[PATCH] D46568: [SimplifyCFG] Fix a crash when folding PHIs

I've slowly come to always prefer the smallest possible test case, since anything else makes it impossible for future readers to determine what the test is supposed to be testing and it is very easy to end up with cargo-cult testcases that don't test anything interesting after a while.
