2020-09-02pretty: trim paths of unique symbolsDan Aloni-13/+13
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.

2019-10-15Use structured suggestion for restricting boundsEsteban Küber-15/+36
When a trait bound is not met and restricting a type parameter would make the restriction hold, use a structured suggestion pointing at an appropriate place (type param in param list or `where` clause). Account for opaque parameters where instead of suggesting extending the `where` clause, we suggest appending the new restriction: `fn foo(impl Trait + UnmetTrait)`.
