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