Ah, the reason why pr19210-* fail is that those loops have non-const/pure call
in it. So, while single_exit (loop) == exit, loop_only_exit_p (loop, exit)
still returns false.
So, the question is if we really need to give up on -funsafe-loop-optimizations
whenever loop_only_exit_p (loop, exit), or if a single_exit (loop) == exit
test would be sufficient for that.
