Synopsis
 _mm512_mask_cvtusepi64_epi8(__m128i src, __mmask8 k, __m512i a);
Description
Convert packed unsigned 64-bit integers in "a" to packed unsigned 8-bit integers with unsigned saturation, 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 7
	i := 64*j
	l := 8*j
	IF k[j]
		dst[l+7:l] := SaturateU8(a[i+63:i])
	ELSE
		dst[l+7:l] := src[l+7:l]
	FI
ENDFOR
dst[MAX:64] := 0
