--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For aarch64 to_lower_1/to_lower_2 is better:

        and     w0, w0, 255
        sub     w1, w0, #65
        and     w1, w1, 255
        cmp     w1, 25
        cset    w1, ls
        add     w0, w0, w1, lsl 5
        ret

vs
        and     w0, w0, 255
        sub     w2, w0, #65
        add     w1, w0, 32
        and     w2, w2, 255
        and     w1, w1, 255
        cmp     w2, 25
        csel    w0, w0, w1, hi
        ret
