Synopsis
 _mm512_shldv_epi64(__m512i a, __m512i b, __m512i c);
Description
Concatenate packed 64-bit integers in "a" and "b" producing an intermediate 128-bit result. Shift the result left by the amount specified in the corresponding element of "c", and store the upper 64-bits in "dst".
Operation
FOR j := 0 to 7
	i := j*64
	tmp[127:0] := ((a[i+63:i] << 64)[127:0] | b[i+63:i]) << (c[i+63:i] & 63)
	dst[i+63:i] := tmp[127:64]
ENDFOR
dst[MAX:512] := 0
