	* i386.h (i386_optab): paddq and psubq, even in their MMX form, are
	available only with SSE2. Change the MMX additions introduced by SSE
	and 3DNow!A to CpuMMX2 (rather than CpuMMX). Indicate the 3DNow!A
	instructions by their now designated identifier (since combining i686
	and 3DNow! does not really imply 3DNow!A).
