ipa-pure-const.c (check_decl): Do not test TYPE_NEEDS_CONSTRUCTING.


	* ipa-pure-const.c (check_decl): Do not test TYPE_NEEDS_CONSTRUCTING.
	* lto-streamer-out.c (hash_tree): Do not hash TYPE_NEEDS_CONSTRUCTING.
	* tree-streamer-in.c (unpack_ts_type_common_value_fields): Do not
	stream TYPE_NEEDS_CONSTRUCTING.
	* tree-streamer-out.c (pack_ts_type_common_value_fields): Likewise.
	* tree.c (free_lang_data_in_type): Clear TYPE_NEEDS_CONSTRUCTING.
