If the goal is to check other patches, you can probably use simpler func,
but "really" adapt for AVX512
like blockdsp and/or losslessvideodsp->addbytes, who can probably switch to
AVX512, without lot of work
for losslessvideodsp, (see libavcodec/lossless_videodsp : add add_bytes
AVX2 discussion (not yet apply))
the mmsize, is basically enough to make basic test
Both have checkasm already write, and can really test the "zmm part"
