pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not. 2020-09-02 02:40:56 -05:00			error[E0277]: the trait bound `X: Ord` is not satisfied

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*`).
