14195 OPERAND_ADDRESS when computing how many registers an insn needs.
14196 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
14198 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
14199 OPADDR_ADDR reload.
14200 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
14201 in reload_reg_use_in_op_addr do not reach the end.
14202 do not reach the end.
14203 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
14204 RELOAD_FOR_OPERAND_ADDRESS.
