Synopsis
 _mm256_slli_epi64(__m256i a, int imm8);
Description
Shift packed 64-bit integers in "a" left by "imm8" while shifting in zeros, and store the results in "dst".
Operation
FOR j := 0 to 3
	i := j*64
	IF imm8[7:0] > 63
		dst[i+63:i] := 0
	ELSE
		dst[i+63:i] := ZeroExtend64(a[i+63:i] << imm8[7:0])
	FI
ENDFOR
dst[MAX:256] := 0
