Synopsis
 _mm512_maskz_slli_epi16(__mmask32 k, __m512i a, unsigned int imm8);
Description
Shift packed 16-bit integers in "a" left by "imm8" 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 31
	i := j*16
	IF k[j]
		IF imm8[7:0] > 15
			dst[i+15:i] := 0
		ELSE
			dst[i+15:i] := ZeroExtend16(a[i+15:i] << imm8[7:0])
		FI
	ELSE
		dst[i+15:i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
