Property get/set on null/undefined should fail

Given:

```js
/** @param {null} name */
function hello(name) {
alert(name.x);
}
hello(null);
```

I expect there to be an error on line 3 since you cannot do `ToObject` on `null`/`undefined`.

This might need a per file/project setting to make it easier to transition to it.
