[RFC 2091] Add #[track_caller] attribute.
- The attribute is behind a feature gate. - Error if both #[naked] and #[track_caller] are applied to the same function. - Error if #[track_caller] is applied to a non-function item. - Error if ABI is not "rust" - Error if #[track_caller] is applied to a trait function. Error codes and descriptions are pending.
