* tree.h (struct record_layout_info_s): New field unpadded_align.
(set_lang_adjust_rli): New declaration.
* stor-layout.c (layout_decl): If DECL is packed, but at alignment
it would have if not packed, do not downgrade DECL_ALIGN.
(lang_adjust_rli, set_lang_adjust_rli): New.
(start_record_layout): Initialize new field unpadded_align.
(debug_rli): Display it.
(place_union_field, place_field): Set it.
(layout_type, case RECORD_TYPE): Call via lang_adjust_rli if set.
