Also note this patch improves (a lot):
```
unsigned char f(long long t)
{
return t < 0;
}
```
Down to:
```
f:
/* prologue: function */
/* frame size = 0 */
/* stack size = 0 */
.L__stack_usage = 0
mov r24,r25
rol r24
clr r24
rol r24
/* epilogue start */
ret
```
Rather than what it was in GCC 13:
```
f:
push r16
ldi r16,lo8(63)
rcall __lshrdi3
mov r24,r18
pop r16
ret
```
