494 to update_alignment_for_field, and recompute it afterwards using
495 the alignment of the record.
496 When a packed bitfield precedes an MS bitfield, don't add padding
497 at the end of the packed bitfield on behalf of the base type of
498 the packed bit field.
499 Don't adjust rli->bitpos at the end
500 of an MS bitfield run if we already adjusted bitpos/offset for an
501 alignment as large or larger than the bitfield type size.
502 Take possible record alignment > BIGGEST_ALIGNMENT into account
503 when calculating actual_align.
504 Only put packed buit fields into rli->prev_field if they end up
506 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
507 Update rli->remaining_in_alignment when we have already started a
