Synopsis
 _mm512_maskz_sqrt_round_pd(__mmask8 k, __m512d a, int rounding);
Description
Compute the square root of packed double-precision (64-bit) floating-point elements in "a", and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). [round_note].
Operation
FOR j := 0 to 7
	i := j*64
	IF k[j]
		dst[i+63:i] := SQRT(a[i+63:i])
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
