Depending on !COMPILE_TEST isn't sufficient to keep this feature out of CI because we can't stop it from being included in randconfig builds. This feature is still highly experimental, and is developed in lock-step with Clang's Overflow Behavior Types[1]. Depend on BROKEN to keep it from being enabled by anyone not expecting it.
