add a per-param-env cache to `impls_bound` There used to be only a global cache, which led to uncached calls to trait selection when there were type parameters. This causes a 20% decrease in borrow-checking time and an overall 0.5% performance increase during bootstrapping (as borrow-checking tends to be a tiny part of compilation time). Fixes #37106 (drop elaboration times are now ~half of borrow checking, so might still be worthy of optimization, but not critical). r? @pnkfelix |
