The spans for "trait bound not satisfied" errors in trivial trait bounds referenced the entire item (fn, impl, struct) before. Now they only reference the obligation itself (`String: Copy`) Address rust-lang#90869

There was a problem hiding this comment.
Ideally this should have a secondary span pointing at line 5, but that can be accomplished with maybe a new ObligationCauseCode (or maybe an ImplObligation).
