The feature gating behavior may be shortened and kept cleaner using the default visitor. This means less maintenance on visit functions as the traversal is shared by multiple visitors. gcc/rust/ChangeLog: * checks/errors/rust-feature-gate.cc (FeatureGate::visit): Add a visit function for the crate level. (FeatureGate::check): Add call to crate visit. * checks/errors/rust-feature-gate.h (class FeatureGate): Remove now useless visit functions (traversal only).
