    tree-optimization/97835 - fix step vector construction for SLP induction

    We're stripping conversions off access functions of inductions and
    thus the step can be of different sign.  Fix bogus step CTORs by
    converting the elements rather than the whole vector.

            * tree-vect-loop.c (vectorizable_induction): Convert step
            scalars rather than step vector.

            * gcc.dg/vect/pr97835.c: New testcase.
