Synopsis
 _mm256_mask_srl_epi16(__m256i src, __mmask16 k, __m256i a, __m128i count);
Description
Shift packed 16-bit integers in "a" right by "count" while shifting in zeros, 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 15
	i := j*16
	IF k[j]
		IF count[63:0] > 15
			dst[i+15:i] := 0
		ELSE
			dst[i+15:i] := ZeroExtend16(a[i+15:i] >> count[63:0])
		FI
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI
ENDFOR
dst[MAX:256] := 0
