        * gfortran.h (symbol_attribute): Add artificial.
        * module.c (mio_symbol_attribute): Handle attr.artificial
        * class.c (gfc_build_class_symbol): Defer creation of the vtab
        if the DT has finalizers, mark generated symbols as
        attr.artificial.
        (has_finalizer_component, finalize_component,
        finalization_scalarizer, generate_finalization_wrapper):
        New static functions.
        (gfc_find_derived_vtab): Add _final component and call
        generate_finalization_wrapper.
        * dump-parse-tree.c (show_f2k_derived): Use resolved
        proc_tree->n.sym rather than unresolved proc_sym.
        (show_attr): Handle attr.artificial.
        * resolve.c (gfc_resolve_finalizers): Ensure that the vtab
        * exists.
        (resolve_fl_derived): Resolve finalizers before
        generating the vtab.
        (resolve_symbol): Also allow assumed-rank arrays with CONTIGUOUS;
        skip artificial symbols.
        (resolve_fl_derived0): Skip artificial symbols.
