        * tree-vectorizer.h (vect_get_smallest_scalar_type): Declare.
        * tree-vect-analyze.c (vect_get_smallest_scalar_type): New function.
        (vect_determine_vectorization_factor): Move the scalar type
        retrieval to vect_get_smallest_scalar_type.
        (vect_build_slp_tree): Call vect_get_smallest_scalar_type to get
        scalar type. Remove redundant computation.
        * tree-vect-transform.c (vect_get_constant_vectors): Add argument.
        (vect_get_slp_defs): Take the type of RHS into account if
        necessary by calling vect_get_smallest_scalar_type. Call
        vect_get_constant_vectors with additional argument.
