Synopsis
 _mm512_maskz_cvtt_roundpd_epu64(__mmask8 k, __m512d a, int sae);
Description
Convert packed double-precision (64-bit) floating-point elements in "a" to packed unsigned 64-bit integers with truncation, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). [sae_note]
Operation
FOR j := 0 to 7
	i := j*64
	IF k[j]
		dst[i+63:i] := Convert_FP64_To_UInt64_Truncate(a[i+63:i])
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
