    tree-optimization/106189 - avoid division by zero exception

    The diagnostic code can end up with zero sized array elements
    with T[][0] and the wide-int code nicely avoids exceptions when
    dividing by zero in one codepath but not in another.  The following
    fixes the exception by using wide-int in both paths.

            * gimple-array-bounds.cc (array_bounds_checker::check_mem_ref):
            Divide using offset_ints.

            * gcc.dg/pr106189.c: New testcase.
