1405 (place_field): At the beginning of a record, pass 0 as KNOWN_ALIGN
1406 to update_alignment_for_field, and recompute it afterwards using
1407 the alignment of the record.
1408 When a packed bitfield precedes an MS bitfield, don't add padding
1409 at the end of the packed bitfield on behalf of the base type of
1410 the packed bit field.
1411 Don't adjust rli->bitpos at the end
1412 of an MS bitfield run if we already adjusted bitpos/offset for an
1413 alignment as large or larger than the bitfield type size.
1414 Take possible record alignment > BIGGEST_ALIGNMENT into account
1415 when calculating actual_align.
1416 Only put packed buit fields into rli->prev_field if they end up
1418 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
1419 Update rli->remaining_in_alignment when we have already started a
1420 run of bit fields and we process a packed bit field.
