1835 * stor-layout.c (update_alignment_for_field): Fix comment about
1836 KNOWN_ALIGN. For MS bitfields, if we start a new run, make sure
1837 we start it properly aligned.
1838 (place_field): At the beginning of a record, pass 0 as KNOWN_ALIGN
1839 to update_alignment_for_field, and recompute it afterwards using
1840 the alignment of the record.
1841 When a packed bitfield precedes an MS bitfield, don't add padding
1842 at the end of the packed bitfield on behalf of the base type of
1843 the packed bit field.
1844 Don't adjust rli->bitpos at the end
1845 of an MS bitfield run if we already adjusted bitpos/offset for an
1846 alignment as large or larger than the bitfield type size.
1847 Take possible record alignment > BIGGEST_ALIGNMENT into account
1848 when calculating actual_align.
1849 Only put packed buit fields into rli->prev_field if they end up
1851 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
1852 Update rli->remaining_in_alignment when we have already started a
1853 run of bit fields and we process a packed bit field.

13271 compile-time arithmetic. Return NULL on (internal) overflow.
