…Um. Is this worth the regression? NibbleSort and PhoneBook are both actual sorting tests, no?

NibbleSort is kind of a pathological case, but we do care about PhoneBook. But it's easier to debug why the hand-specialization is needed after landing on master. We can revert if it can't be figured out in time for 5.0. I raised https://bugs.swift.org/browse/SR-8267 to track that.

Also, note this isn't just for the sake of de-gybbing, this was code bloat in the std lib (two near-identical copies of multiple functions)
