Point at source of trait bound obligations in more places Be more thorough in using `ItemObligation` and `BindingObligation` when evaluating obligations so that we can point at trait bounds that introduced unfulfilled obligations. We no longer incorrectly point at unrelated trait bounds (`substs-ppaux.verbose.stderr`). In particular, we now point at trait bounds on method calls. We no longer point at "obvious" obligation sources (we no longer have a note pointing at `Trait` saying "required by a bound in `Trait`", like in `associated-types-no-suitable-supertrait*`).
