gccrs: unsafe: check use of `target_feature` attribute
The `target_feature` attribute is for conditional compilation and may or may not compile on all platforms. Using it requires an unsafe function or block. gcc/rust/ChangeLog: * checks/errors/rust-unsafe-checker.cc (check_target_attr): New function. (UnsafeChecker::check_function_attr): Call into `check_target_attr`. (UnsafeChecker::visit): Check for target_feature attributes. * checks/errors/rust-unsafe-checker.h: Add declarations. * util/rust-attributes.cc: Add attribute. gcc/testsuite/ChangeLog: * rust/compile/unsafe11.rs: New test.
