* config/rx/rx.h (enum rx_cpu_type): Add RX200.

        used together.
        (OVERRIDE_OPTIONS): Delete.
        (OPTIMIZATION_OPTIONS): Define.
        (ALLOW_RX_FPU_INSNS): Define only in terms of -fpu option.

        -mcpu=rx200 and -fpu are used together.
        (rx_set_optimization_options): New function.  Issue an error
        message if an optimization attribute attempts to reset the FPU/
        math optimization pairing.
        * config/rx/rx-protos.h (rx_set_optimization_options): Prototype.
        * config/rx/rx.opt: Set the default to 32-bit doubles.
