AVR: Don't asm output operations for unused result bytes.
When REG_UNUSED notes indicate that some result bytes are not
used by the following code, then there's no need to asm out them.
The patch uses such notes for the asm out of AND, IOR, XOR, PLUS, MINUS.
gcc/
* config/avr/avr.cc (avr_result_regno_unused_p): New static function.
(avr_out_bitop): Only output result bytes that are used.
(avr_out_plus_1): Same.
