Synopsis
 _mm512_mask_cvtne2ps_pbh(__m512bh src, __mmask32 k, __m512 a, __m512 b);
Description
Convert packed single-precision (32-bit) floating-point elements in two vectors "a" and "b" to packed BF16 (16-bit) floating-point elements, and store the results in single vector "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
	IF k[j]
		IF j < 16
			t := b.fp32[j]
		ELSE
			t := a.fp32[j-16]
		FI
		dst.word[j] := Convert_FP32_To_BF16(t)
	ELSE
		dst.word[j] := src.word[j]
	FI
ENDFOR
dst[MAX:512] := 0
