rs6000: Delete HAVE_AS_DCI

Browse Source 
Every supported assembler supports these instructions.  Committing.


	* config.in: Delete HAVE_AS_DCI.
	* config/powerpcspe/powerpcspe.h: Treat HAVE_AS_DCI as always true.
	* config/rs6000/rs6000.h: Ditto.
	* configure.ac: Delete HAVE_AS_DCI.
	* configure: Regenerate.
