gccrs: Add feature gate for "rust-intrinsic".

This commit implemented a feature gate to check `intrinsics`.

gcc/rust/ChangeLog:

	* checks/errors/rust-feature-gate.cc: Add implementation for
	`void FeatureGate::visit (AST::ExternBlock &block)`. Add `valid_feature`
	construction process in `FeatureGate::check`.
	* checks/errors/rust-feature-gate.h: Add declaration for
	`void FeatureGate::visit (AST::ExternBlock &block)`. Add private
	variable `valid_feature`.
	* checks/errors/rust-feature.h: Change `issue` to `m_issue`.

gcc/testsuite/ChangeLog:

	* rust/compile/const-issue1440.rs: Add crate feature: `intrinsics`.
	* rust/compile/feature_intrinsics.rs: New file.
	* rust/compile/issue-1031.rs: Add crate feature: `intrinsics`.
