This and the one below are drive-by changes. These shouldn't ever be displayed anyways. But wanted to stop using from_obligation_cause (was potentially going a different direction for this PR).

This bound was required because of a bug that has since been fixed. FIXME still stands for the two remaining though.

Suggest copying trait associated type bounds on lifetime error Closes rust-lang#92033 Kind of the most simple suggestion to make - we don't try to be fancy. Turns out, it's still pretty useful (the couple existing tests that trigger this error end up fixed - for this error - upon applying the fix). r? `@estebank` cc `@nikomatsakis`
