    vect: Adjust vect_transform_reduction assertion [PR114883]

    The assertion doesn't allow IFN_COND_MIN/IFN_COND_MAX, which are
    commutative conditional binary operations like ADD/MUL/AND/IOR/XOR,
    and can be handled just fine.
    In particular, we emit
            vminpd  %zmm3, %zmm5, %zmm0{%k2}
            vminpd  %zmm0, %zmm3, %zmm5{%k1}
    and
            vmaxpd  %zmm3, %zmm5, %zmm0{%k2}
            vmaxpd  %zmm0, %zmm3, %zmm5{%k1}
    in the vectorized loops of the first and second subroutine.
