        PR lto/83804
        * tree.c (free_lang_data_in_type): Always unlink TYPE_DECLs
        from TYPE_FIELDS.  Free TYPE_BINFO if not used by devirtualization.
        Reset type names to their identifier if their TYPE_DECL doesn't
        have linkage (and thus is used for ODR and devirt).
        (save_debug_info_for_decl): Remove.
        (save_debug_info_for_type): Likewise.
        (add_tree_to_fld_list): Adjust.
        * tree-pretty-print.c (dump_generic_node): Make dumping of
        type names more robust.
