lto-streamer-out.c (lto_variably_modified_type_p): New.
2019-10-15 Richard Biener <rguenther@suse.de>
* lto-streamer-out.c (lto_variably_modified_type_p): New.
(tree_is_indexable): Use it.
* tree-streamer-out.c (pack_ts_type_common_value_fields):
Stream variably_modified_type_p as TYPE_LANG_FLAG_0.
* tree-streamer-in.c (unpack_ts_type_common_value_fields): Likewise.
