Auto merge of #65874 - Nadrieril:clarify-usefulness, r=varkor
Clarify pattern-matching usefulness algorithm This PR clarifies a bit the usefulness algorithm by emphasizing that each row of the matrix can be seen as a sort of stack from which we pop constructors. It also moves code around to increase separation of concerns. This is part of my splitting of https://github.com/rust-lang/rust/pull/65160 into smaller PRs.
