Ilya Yanok 6c61db4407 Use is_global in candidate_should_be_dropped_in_favor_of ... This manifistated in #90195 with compiler being unable to keep one candidate for a trait impl, if where is a global impl and more than one trait bound in the where clause. Before #87280 `candidate_should_be_dropped_in_favor_of` was using `TypeFoldable::is_global()` that was enough to discard the two `ParamCandidate`s. But #87280 changed it to use `TypeFoldable::is_known_global()` instead, which is pessimistic, so now the compiler drops the global impl instead (because `is_known_global` is not sure) and then can't decide between the two `ParamCandidate`s. Switching it to use `is_global` again solves the issue. Fixes #90195.		2021-10-28 12:49:46 +00:00
