Synopsis
 _mm512_mask_sll_epi32(__m512i src, __mmask16 k, __m512i a, __m128i count);
Description
Shift packed 32-bit integers in "a" left 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*32
	IF k[j]
		IF count[63:0] > 31
			dst[i+31:i] := 0
		ELSE
			dst[i+31:i] := ZeroExtend32(a[i+31:i] << count[63:0])
		FI
	ELSE
		dst[i+31:i] := src[i+31:i]
	FI
ENDFOR
dst[MAX:512] := 0
