Synopsis
 _mm512_mask_cvtxph_ps(__m512 src, __mmask16 k, __m256h a);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed single-precision (32-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).
Operation
FOR j := 0 to 15
	IF k[j]
		dst.fp32[j] := Convert_FP16_To_FP32(a.fp16[j])
	ELSE
		dst.fp32[j] := src.fp32[j]
	FI
ENDFOR
dst[MAX:512] := 0
