* stor-layout.c (finish_bitfield_representative): Fallback
to conservative maximum size if the padding up to the next
field cannot be computed as a constant.
(finish_bitfield_layout): If we cannot compute the distance
between the start of the bitfield representative and the
bitfield member start a new representative.
* expr.c (get_bit_range): The distance between the start of
the bitfield representative and the bitfield member is zero
if the field offsets are not constants.
* gnat.dg/pack16.adb: New testcase.
* gnat.dg/pack16_pkg.ads: Likewise.
* gnat.dg/specs/pack8.ads: Likewise.
* gnat.dg/specs/pack8_pkg.ads: Likewise.
