e088016f9d Let ctor_sub_tys return any Iterator they want
Since we always clone and allocate the types somewhere else ourselves,
no need to ask for `Cx` to do the allocation.

Rollup merge of #119835 - Nadrieril:simplify-empty-logic, r=compiler-errors
Exhaustiveness: simplify empty pattern logic

The logic that handles empty patterns had gotten quite convoluted. This PR simplifies it a lot. I tried to make the logic as easy as possible to follow; this only does logically equivalent changes.

The first commit is a drive-by comment clarification that was requested after another PR a while back.

bf913ad0ae Simplify use of ValidityConstraint
We had reached a point where the shenanigans about omitting empty arms
are unnecessary.

It was only used to track types and relevancy, so may as well store that
directly.
