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.

Mention implementers of unsatisfied trait When encountering an unsatisfied trait bound, if there are no other suggestions, mention all the types that *do* implement that trait: ``` error[E0277]: the trait bound `f32: Foo` is not satisfied --> $DIR/impl_wf.rs:22:6 | LL | impl Baz<f32> for f32 { } | ^^^^^^^^ the trait `Foo` is not implemented for `f32` | = help: the following other types implement trait `Foo`: Option<T> i32 str note: required by a bound in `Baz` --> $DIR/impl_wf.rs:18:31 | LL | trait Baz<U: ?Sized> where U: Foo { } | ^^^ required by this bound in `Baz` ``` Mention implementers of traits in `ImplObligation`s. Do not mention other `impl`s for closures, ranges and `?`.
