Synopsis
 _mm256_mask_cvttpd_epi64(__m256i src, __mmask8 k, __m256d a);
Description
Convert packed double-precision (64-bit) floating-point elements in "a" to packed 64-bit integers with truncation, 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 3
	i := j*64
	IF k[j]
		dst[i+63:i] := Convert_FP64_To_Int64_Truncate(a[i+63:i])
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
dst[MAX:256] := 0
