Auto merge of #43723 - arielb1:nonincremental-fast-reject, r=eddyb
make `for_all_relevant_impls` O(1) again A change in #41911 had made `for_all_relevant_impls` do a linear scan over all impls, instead of using an HashMap. Use an HashMap again to avoid quadratic blowup when there is a large number of structs with impls. I think this fixes #43141 completely, but I want better measurements in order to be sure. As a perf patch, please don't roll this up. r? @eddyb beta-nominating because regression
