Synopsis
 _mm256_maskz_srlv_epi64(__mmask8 k, __m256i a, __m256i count);
Description
Shift packed 64-bit integers in "a" right by the amount specified by the corresponding element in "count" while shifting in zeros, 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 3
	i := j*64
	IF k[j]
		IF count[i+63:i] < 64
			dst[i+63:i] := ZeroExtend64(a[i+63:i] >> count[i+63:i])
		ELSE
			dst[i+63:i] := 0
		FI
	ELSE
		dst[i+63:i] := 0
	FI	
ENDFOR
dst[MAX:256] := 0
