1411 to update_alignment_for_field, and recompute it afterwards using
1412 the alignment of the record.
1413 When a packed bitfield precedes an MS bitfield, don't add padding
1414 at the end of the packed bitfield on behalf of the base type of
1415 the packed bit field.
1416 Don't adjust rli->bitpos at the end
1417 of an MS bitfield run if we already adjusted bitpos/offset for an
1418 alignment as large or larger than the bitfield type size.
