`maytrap` just prevents speculatively executing instructions that could raise
an exception. It doesn't guarantee strict exception semantics. It also doesn't
make any guarantees about rounding mode, though in practice you get that as a
side effect. Should we be recommending '-ffp-model=strict' instead or at least
mentioning it as an alternative?
