Turns out that writing to global state is more expensive than writing to
a property on an object.
Slower:
````
let count = 0;
function increment() {
count++;
}
```
Faster:
````
const state = {
count: 0
};
function increment() {
state.count++;
}
```
This change moves all of the instruction state into a single state object.
