    gccrs: ast: Add TokenStream collect function
    
    Add a function to TokenStream to collect in a single vector all tokens.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-tokenstream.cc (TokenStream::collect_tokens): Add
            getter.
            (TokenStream::go): Rename function.
            (TokenStream::visit): Likewise.
            * ast/rust-ast-tokenstream.h: Add collect prototype.
