	* config/tc-i386.h (CpuMMX2): Declare. Artificial classifier to
	indicate the MMX extensions added by both SSE and 3DNow!A.
	(Cpu3dnowA): Declare.
	(CpuUnknownFlags): Update.
	* config/tc-i386.c (cpu_sub_arch_name): Declare.
	(cpu_arch): i586 and pentium do not imply MMX. i686 and pentiumpro do
	neither imply SSE nor MMX. k6 implies MMX. k6_2 additionally implies
	3DNow!. Athlon additionally implies 3DNow!A. Several new
	entries (those starting with a dot are for sub-arch specification).
	(set_cpu_arch): Handle sub-arch specifications.
	(parse_insn): Distinguish between instructions not supported because
	of insufficient CPU features and because of 64-bit mode.
	* doc/c-i386.texi: Describe enhanced .arch directive.

	* 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).
