Add existing behaviour test for deref suggestions. This commit adds a test that demonstrates the current behaviour where suggestions to add a dereference aren't given for non-references.

error[E0308]: mismatched types
Only make suggestion when type is `Copy`. This commit makes the suggestion to dereference when a type implements `Deref` only apply if the dereference would succeed (ie. the type is `Copy`, otherwise a borrow check error would occur).

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.
