    middle-end/113396 - int128 array index and value-ranges

    The following fixes bogus truncation of a value-range for an int128
    array index when computing the maximum extent for a variable array
    reference.  Instead of possibly slowing things down by using
    widest_int the following makes sure the range bounds fit within
    the constraints offset_int were designed for.

            PR middle-end/113396
            * tree-dfa.cc (get_ref_base_and_extent): Use index range
            bounds only if they fit within the address-range constraints
            of offset_int.
