    tree-optimization/95219 - improve IV selection for induction

    This improves code generation with SSE2 for the testcase by
    making sure to only generate a single IV when the group size
    is a multiple of the vector size.  It also adjusts the testcase
    which was passing before.

            * tree-vect-loop.c (vectorizable_induction): Reduce
            group_size before computing the number of required IVs.
