    tree-optimization/110043 - avoid overflow in pointer-query

    pointer-query is built around using offset_int to avoid needing
    to deal with overflow.  This falls apart when trying to analyze
    array accesses indexed by __int128.  So don't.

            PR tree-optimization/110043
            * pointer-query.cc (get_offset_range): Fail for integer
            types with precision larger than ptrdiff_type_node.

            * gcc.dg/torture/pr110043.c: New testcase.
