    * cgraphclones.c (duplicate_thunk_for_node): Removed parameter
    args_to_skip, use those from node instead.  Copy args_to_skip and
    combined_args_to_skip from node to the new thunk.
    (redirect_edge_duplicating_thunks): Removed parameter args_to_skip.
    (cgraph_create_virtual_clone): Moved computation of
    combined_args_to_skip...
    (cgraph_clone_node): ...here, simplify it to bitmap_ior..
