    tree-optimization/117119 - ICE with int128 IV in dataref analysis

    Here's another fix for a missing check that an IV value fits in a
    HIW.  It's originally from Stefan.

            PR tree-optimization/117119
            * tree-data-ref.cc (initialize_matrix_A): Check whether
            an INTEGER_CST fits in HWI, otherwise return chrec_dont_know.

            * gcc.dg/torture/pr117119.c: New testcase.
