2bfd919b6a Narrow on element access of literal (#26424) 
* Narrow literal element accesses

This means that, for example, the tuple `[number, string?]` allows its
second element to be narrowed with element access:

```ts
export function f(pair: [number, string?]): string {
  return pair[1] ? pair[1] : 'nope';
}
```

* Cleanup

* More cleanup

* Test dashes in property names
