Auto merge of #51460 - nikomatsakis:nll-perf-examination-refactor-1, r=pnkfelix
Improve memoization and refactor NLL type check I have a big branch that is refactoring NLL type check with the goal of introducing canonicalization-based memoization for all of the operations it does. This PR contains an initial prefix of that branch which, I believe, stands alone. It does introduce a few smaller optimizations of its own: - Skip operations that are trivially a no-op - Cache the results of the dropck-outlives computations done by liveness - Skip resetting unifications if nothing changed r? @pnkfelix
