resolve: prohibit foreign statics w/ generics This commit modifies resolve to disallow foreign statics that use parent generics. `improper_ctypes` is not written to support type parameters, as these are normally disallowed before the lint is run. Thus, type parameters in foreign statics must be prohibited before the lint. The only other case where this could have occured is in functions, but typeck prohibits this with a "foreign items may not have type parameters" error - a similar error did not exist for statics, because statics cannot have type parameters, but they can use any type parameters that are in scope (which isn't the case for functions).

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 09:40:56 +02:00			= help: consider removing `T`, referring to it in a field, or using a marker such as `PhantomData`
