--- Comment #12 from Andrew Trick <atrick at apple.com> ---
Fixed on trunk r182989.

I found a way to avoid the incorrect assumption about undefined behavior while
still optimizing the common case. Loop exits controlled by 'or' expressions
should now be optimized the same (conservative) way as loops with multiple
exits.
