I have a slight problem with these kinds of Lit features, because what's considered "large" or "slow" is entirely subjective. This is also the reason why `long-tests` is not a great Lit parameter, and in fact I've contemplated removing it IDK how many times.

Instead, I think it would be better to have a way to exclude tests that time out after a certain amount of time, or that bypass some system limits like rlimits. WDYT?
