    tree-optimization/97732 - fix init of SLP induction vectorization

    This PR exposes two issues - one that the vector builder treats
    &x as eligible for VECTOR_CST elements and one that SLP induction
    vectorization forgets to convert init elements to the vector
    component type which makes a difference for pointer vs. integer.

            * tree-vect-loop.c (vectorizable_induction): Convert the
            init elements to the vector component type.
            * gimple-fold.c (gimple_build_vector): Use CONSTANT_CLASS_P
            rather than TREE_CONSTANT to determine if elements are
            eligible for VECTOR_CSTs.
