    gccrs: ast: Fix inner attribute tokenstream
    
    Inner attribute did not output exclamation tokens as there was no way to
    differentiate inner from outer attributes previously.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-tokenstream.cc (TokenStream::visit): Fix inner
            attribute tokenstream output.
