poly_int: store_bit_field bitrange
This patch changes the bitnum and bitsize arguments to
store_bit_field from unsigned HOST_WIDE_INTs to poly_uint64s.
The later part of store_bit_field_1 still needs to operate
on constant bit positions and sizes, so the patch splits
it out into a subfunction (store_integral_bit_field).

* expmed.h (store_bit_field): Take bitsize and bitnum as
poly_uint64s rather than unsigned HOST_WIDE_INTs.
* expmed.c (simple_mem_bitfield_p): Likewise. Add a parameter
that returns the byte size.
(store_bit_field_1): Take bitsize and bitnum as
poly_uint64s rather than unsigned HOST_WIDE_INTs. Update call
to simple_mem_bitfield_p. Split the part that can only handle
constant bitsize and bitnum out into...
(store_integral_bit_field): ...this new function.
(store_bit_field): Take bitsize and bitnum as poly_uint64s rather
than unsigned HOST_WIDE_INTs.
(extract_bit_field_1): Update call to simple_mem_bitfield_p.
