Auto merge of #24527 - nikomatsakis:issue-24085, r=nikomatsakis
Expand the "givens" set to cover transitive relations. The givens array stores relationships like `'c <= '0` (where `'c` is a free region and `'0` is an inference variable) that are derived from closure arguments. These are (rather hackily) ignored for purposes of inference, preventing spurious errors. The current code did not handle transitive cases like `'c <= '0` and `'0 <= '1`. Fixes #24085. r? @pnkfelix cc @bkoropoff *But* I am not sure whether this fix will have a compile-time hit. I'd like to push to try branch observe cycle times.
