/* This code shows up in worse_state in ipa-pure-const.cc:
*looping = MAX (*looping, looping2);
was miscompiling it as just `return 1` though instead of
`MAX_EXPR<*a, b>` (which should be transformed into `*a | b`
note MAX_EXPR<bool, bool> is really `bool | bool` so we
use that to compare against here.
