* tree-streamer-out.c (pack_ts_type_common_value_fields): Stream if type
	is complete.
	(write_ts_type_common_tree_pointers): Do not stream fields not set for incomplete
	types; do not stream duplicated fields for variants; sanity check that variant
	and type match.
	(write_ts_type_non_common_tree_pointers): Likewise.
	* tree-streamer-in.c (unpack_ts_type_common_value_fields): Mark in TYPE_SIZE whether
	type is complete.
	(lto_input_ts_type_common_tree_pointers): Do same changes as in
	write_ts_type_common_tree_pointers
	(lto_input_ts_type_non_common_tree_pointers): Likewise.

	* lto.c (lto_copy_fields_not_streamed): New function.
	(compare_tree_sccs_1): Do not compare fields shared in between type
	and variant.
	(lto_read_decls): Fixup types first before inserting into hash.
