Synopsis
 _mm256_mask_cvt_roundps_ph(__m128i src, __mmask8 k, __m256 a, int imm8);
Description
Convert packed single-precision (32-bit) floating-point elements 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). [round_imm_note]
Operation
FOR j := 0 to 7
	i := 16*j
	l := 32*j
	IF k[j]
		dst[i+15:i] := Convert_FP32_To_FP16(a[l+31:l])
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI
ENDFOR
dst[MAX:128] := 0
