    tree-vect-generic: Tweak build_replicated_const [PR94980 2/3]

    This patch makes build_replicated_const take the number of bits
    in VALUE rather than calculating the width from the element type.
    The callers can then use vector_element_bits to calculate the
    correct element size from the vector type.

            * tree-vect-generic.c (build_replicated_const): Take the number
            of bits as a parameter, instead of the type of the elements.
            (do_plus_minus): Update accordingly, using vector_element_bits
            to calculate the correct number of bits.
            (do_negate): Likewise.
