  This code was dead in the block where it lived,
because avr_adiw_reg_p() is only true when ADIW and SBIW
are available -- which is not the case for AVR_TINY.

AVR: Dead code removal.

gcc/
         * config/avr/avr.cc (avr_out_compare) [AVR_TINY]: Remove code in
         an "if avr_adiw_reg_p()" block that's dead for AVR_TINY.
