Emit error on auto-traits
Throw an error when auto-traits used without feature attribute.
gcc/rust/ChangeLog:
* checks/errors/rust-feature-gate.cc (FeatureGate::visit): Emit error
on trait when auto field member true.
* checks/errors/rust-feature-gate.h: add prototype of trait visitor.
* checks/errors/rust-feature.cc (Feature::create): add
optin_builtin_traits in match of feature.
gcc/testsuite/ChangeLog:
* rust/compile/auto_trait_super_trait.rs: Add feature attribute.
* rust/compile/generic_auto_trait.rs: likewise.
* rust/compile/auto_trait.rs: add test for error without
feature attribute
