2745 (place_field): At the beginning of a record, pass 0 as KNOWN_ALIGN
2746 to update_alignment_for_field, and recompute it afterwards using

2748 When a packed bitfield precedes an MS bitfield, don't add padding
2749 at the end of the packed bitfield on behalf of the base type of
2750 the packed bit field.
2751 Don't adjust rli->bitpos at the end
2752 of an MS bitfield run if we already adjusted bitpos/offset for an
2753 alignment as large or larger than the bitfield type size.
2754 Take possible record alignment > BIGGEST_ALIGNMENT into account

2758 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
2759 Update rli->remaining_in_alignment when we have already started a
