Handle polynomial DR_INIT
The idea with the main 107-patch poly_int series (latterly 109-patch)
was to change the mode sizes and vector element counts to poly_int and
then propagate those changes as far as they needed to go to fix build
failures from incompatible types. This means that DR_INIT is now
constructed as a poly_int64:
poly_int64 pbytepos;
if (!multiple_p (pbitpos, BITS_PER_UNIT, &pbytepos))
{
if (dump_file && (dump_flags & TDF_DETAILS))
fprintf (dump_file, "failed: bit offset alignment.\n");
return false;
}
[...]
init = ssize_int (pbytepos);
This patch adjusts other references to DR_INIT accordingly. Unlike
the above, the adjustments weren't needed to avoid a build-time type
incompatibility, but they are needed to make the producer and consumers
of DR_INIT logically consistent.

* tree-predcom.c (aff_combination_dr_offset): Use wi::to_poly_widest
rather than wi::to_widest for DR_INITs.
* tree-vect-data-refs.c (vect_find_same_alignment_drs): Use
wi::to_poly_offset rather than wi::to_offset for DR_INIT.
(vect_analyze_data_ref_accesses): Require both DR_INITs to be
INTEGER_CSTs.
(vect_analyze_group_access_1): Note that here.
