Synopsis
 _mm512_mask_avg_epu8(__m512i src, __mmask64 k, __m512i a, __m512i b);
Description
Average packed unsigned 8-bit integers in "a" and "b", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 63
	i := j*8
	IF k[j]
		dst[i+7:i] := (a[i+7:i] + b[i+7:i] + 1) >> 1
	ELSE
		dst[i+7:i] := src[i+7:i]
	FI
ENDFOR
dst[MAX:512] := 0
