Optimize inputs -> counter -> trigger always

There is an autogenerated node pattern that can be easily optimized. When a counter is attached to an input to produce timers but the timers are always triggered, there is no need for the intermediate counter:

See:

```
(system input 3 always) => counter 1025 using copy_latest_a
(counter 1025 always && constant 1034 when value == 1) => counter 1031 using copy_latest_a
```

This should be just:

```
(system input 3 always && constant 1034 when value == 1) => counter 1031 using copy_latest_a
```
