Synopsis
 _mm512_maskz_cvtusepi16_epi8(__mmask32 k, __m512i a);
Description
Convert packed unsigned 16-bit integers in "a" to packed unsigned 8-bit integers with unsigned saturation, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
	i := 16*j
	l := 8*j
	IF k[j]
		dst[l+7:l] := SaturateU8(a[i+15:i])
	ELSE
		dst[l+7:l] := 0
	FI
ENDFOR
dst[MAX:256] := 0
