Research direction
Start by reading RFC 2386 and inspect the gccrs attribute-handling entry points for existing built-in attributes. Implement support for #[used] and the used_with_arg variants #[used(compiler)] and #[used(linker)], then verify behavior with the compiler's relevant attribute tests.
