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.
