[optim] All nested properties in refs are ref values

Forget currently removes memoization of callbacks that have `mutate` effects on 
`ref` inner properties. @gsathya pointed out that our existing compiler behavior 
is to (1) NOT extend mutable ranges for functions that mutate `ref.current` and 
(2) extend mutable ranges for functions that mutate `ref.current.inner`. 

```js 

// input 

function Component() { 

const ref = useRef({ text: null }); 

const handleChange = useCallback((e) => { 

ref.current.text = e.target.value; 

}); 

return <input onChange={handleChange} />; 

} 

// output 

function Component() { 

const ref = useRef({ text: null }); 

// now unmemoized! 

const handleChange = (e) => { 

ref.current.text = e.target.value; 

};
