sse.md (mulv16qi3): Change back from an expander to an insn-and-split. 

* config/i386/sse.md (mulv16qi3): Change back from an expander
	to an insn-and-split.
	(mulv4si): Mention AVX not XOP for AVX exception.
	(*sse2_mulv4si3): Likewise.
	(mulv2di3): Use vmulld not vpmacsdd for XOP expansion.  Tidy.
