Synopsis
 _mm_mask_cvtepi64_ph(__m128h src, __mmask8 k, __m128i a);
Description
Convert packed signed 64-bit integers in "a" to packed half-precision (16-bit) floating-point elements, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). The upper 96 bits of "dst" are zeroed out.
Operation
FOR j := 0 TO 1
	IF k[j]
		dst.fp16[j] := Convert_Int64_To_FP16(a.qword[j])
	ELSE
		dst.fp16[j] := src.fp16[j]
	FI
ENDFOR
dst[MAX:32] := 0
