    * config/avr/avr.md (cc): Add out_plus attribute alternative.

    avr_out_plus for all CONST_INT addends.
    * config/avr/avr-protos.h (avr_out_plus): Change prototype.
    * config/avr/avr.c (notice_update_cc): Call avr_out_plus on
    CC_OUT_PLUS.
    (avr_out_plus_1): Change prototype and report effect on cc0.
    (avr_out_plus): Ditto.
    (adjust_insn_length): Adapt call to avr_out_plus to new prototype.
