3633 (place_field): At the beginning of a record, pass 0 as KNOWN_ALIGN
3634 to update_alignment_for_field, and recompute it afterwards using
3635 the alignment of the record.
3636 When a packed bitfield precedes an MS bitfield, don't add padding
3637 at the end of the packed bitfield on behalf of the base type of
3638 the packed bit field.
3639 Don't adjust rli->bitpos at the end
3640 of an MS bitfield run if we already adjusted bitpos/offset for an
3641 alignment as large or larger than the bitfield type size.
3642 Take possible record alignment > BIGGEST_ALIGNMENT into account
3643 when calculating actual_align.
3644 Only put packed buit fields into rli->prev_field if they end up
3646 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
3647 Update rli->remaining_in_alignment when we have already started a
3648 run of bit fields and we process a packed bit field.
