gcc/
* tree-ssa-loop-ivopts.h (strip_offset): Return the offset as
poly_uint64_pod rather than an unsigned HOST_WIDE_INT.
* tree-loop-distribution.c (classify_builtin_st): Update accordingly.
* tree-ssa-loop-ivopts.c (iv_use::addr_offset): Change from
an unsigned HOST_WIDE_INT to a poly_uint64_pod.
(group_compare_offset): Update accordingly.
(split_small_address_groups_p): Likewise.
(record_use): Take addr_offset as a poly_uint64 rather than
an unsigned HOST_WIDE_INT.
(strip_offset): Return the offset as a poly_uint64 rather than
an unsigned HOST_WIDE_INT.
(record_group_use, split_address_groups): Track polynomial offsets.
(add_iv_candidate_for_use): Likewise.
(addr_offset_valid_p): Take the offset as a poly_int64 rather
than a HOST_WIDE_INT.
(strip_offset_1): Return the offset as a poly_int64 rather than
a HOST_WIDE_INT.
