  Former instruction format RRF[-a], where the first operand is in bits
16-19, has been separated into the new RRD format since IBM z196. [1, 2]

	* s390-opc.c (INSTR_RRF_FE0FF, MASK_RRF_FE0FF): Rename to
	INSTR_RRD_FE0FF and MASK_RRD_FE0FF.
	* s390-opc.txt (myr): Use renamed insn format RRD_FE0FF.
