     AVR: avr.cc - Drop a superfluous sub-condition in avr_out_compare.

     In avr.cc::avr_out_compare() there is this condition:

       if (n_bytes == 4
           && eqne_p
           && AVR_HAVE_ADIW
           && REGNO (xreg) >= REG_22
           && (xval == const0_rtx
               || (IN_RANGE (avr_int16 (xval, 2), 0, 63)
                   && eqne_p
                   && reg_unused_after (insn, xreg))))

     where the 2nd sub-expression "&& eqne_p" is superfluous.

     gcc/
             * config/avr/avr.cc (avr_out_compare): Drop superfluous 
sub-condition.
