        * config/i386/sse.md (*andnot<mode>3,
        <mask_codefor><code><mode>3<mask_name>, *<code><mode>3): Split
        (=v,v,vm) alternative into (=x,x,xm) and (=v,v,vm), for 128-bit
        and 256-bit vectors, the (=x,x,xm) alternative and when mask is
        not applied use empty suffix even for TARGET_AVX512VL.
        * config/i386/subst.md (mask_prefix3, mask_prefix4): When mask
        is applied, supply evex,evex or evex,evex,evex instead of just
        evex.
