Synopsis
 _mm512_mask_broadcastb_epi8(__m512i src, __mmask64 k, __m128i a);
Description
Broadcast the low packed 8-bit integer from "a" to all elements of "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 63
	i := j*8
	IF k[j]
		dst[i+7:i] := a[7:0]
	ELSE
		dst[i+7:i] := src[i+7:i]
	FI
ENDFOR
