poly_int: indirect_refs_may_alias_p
This patch makes indirect_refs_may_alias_p use ranges_may_overlap_p
rather than ranges_overlap_p. Unlike the former, the latter can handle
negative offsets, so the fix for PR44852 should no longer be necessary.
It can also handle offset_int, so avoids unchecked truncations to
HOST_WIDE_INT.
