min_exhaustive_patterns provides a subset of the functionality of exhaustive_patterns which is likely to be stabilized much earlier than the full feature.

The subset covers all the compiler and std use cases. compiler/ already uses it; this PR switches std over.

Oh, I claimed too much 🙈. Welp, not much I can do, will come back to this with never_patterns probably

(note for the curious and my future self: with panic = "abort", PoisonError<T> is uninhabited and some std code matches on it under a reference, which is not part of what min_exhaustive_patterns allows).

@Nadrieril I'm a big fan of using the weaker, stabilization-track feature in std. I'd happily r+ this if you re-open and update it to add the TryLockError::Poisoned(never) => match never {}, arms in the 4 places.

Ok! Let's see if that's the only place that needs that.
