953 (place_field): At the beginning of a record, pass 0 as KNOWN_ALIGN
954 to update_alignment_for_field, and recompute it afterwards using
955 the alignment of the record.
956 When a packed bitfield precedes an MS bitfield, don't add padding
957 at the end of the packed bitfield on behalf of the base type of
958 the packed bit field.
959 Don't adjust rli->bitpos at the end
960 of an MS bitfield run if we already adjusted bitpos/offset for an
961 alignment as large or larger than the bitfield type size.
962 Take possible record alignment > BIGGEST_ALIGNMENT into account
963 when calculating actual_align.
964 Only put packed buit fields into rli->prev_field if they end up
966 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
967 Update rli->remaining_in_alignment when we have already started a
