        * config/i386/sse.md (VI248_VLBW): Rename to ...
        (VI248_AVX512VL): ... this.  Don't guard V32HI with TARGET_AVX512BW.
        (vpshrd_<mode><mask_name>, vpshld_<mode><mask_name>,
        vpshrdv_<mode>, vpshrdv_<mode>_mask, vpshrdv_<mode>_maskz,

        vpshldv_<mode>_maskz, vpshldv_<mode>_maskz_1): Use VI248_AVX512VL
        mode iterator instead of VI248_VLBW.
