The lint checks arguments in calls to `transmute` or functions that have `Pointer` as a trait bound and displays a warning if the argument is a function reference. Also checks for `std::fmt::Pointer::fmt` to handle formatting macros although it doesn't depend on the exact expansion of the macro or formatting internals. `std::fmt::Pointer` and `std::fmt::Pointer::fmt` were also added as diagnostic items and symbols.
