* config/frv/frv.md (UNSPEC_MASACCS, UNSPEC_MDASACCS): New constants.

	(maddaccs, msubaccs, *maddacc): Turn operand 0 into a single ACC/ACCG
	pair.  Remove match_dup from inputs.  Remove masaccs handling.
	(mdaddaccs, mdsubaccs, *mdaddacc): Likewise a dual ACC/ACCG pair.
	(masaccs, mdasaccs): Turn into define_insns.
