KNOWN_ALIGN. For MS bitfields, if we start a new run, make sure
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.
