    resolver: Allow SimplePath to resolve to their root segment
    
    SimplePath are allowed to resolve to their root segment even if it is `crate`
    or `super` when checking visibilities. We now have to make sure that this
    is allowed everywhere a SimplePath is kept.
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-ast-resolve-path.cc (ResolvePath::resolve_path): Set
            resolved_node_id when visiting root segment of SimplePath.
