stor-layout.c (place_union_field): If any field was aligned with attribute aligned, set record type's TYPE_USER_ALIGN.

	* stor-layout.c (place_union_field): If any field was aligned with
	attribute aligned, set record type's TYPE_USER_ALIGN.
	(place_field): Likewise.
	(finalize_record_size): Don't clear TYPE_USER_ALIGN.
	(layout_type) [ARRAY_TYPE]: Copy element's TYPE_USER_ALIGN.
