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

This means that, for example, the tuple `[number, string?]` allows its

  return pair[1] ? pair[1] : 'nope';
}
```

* Update baselines

* Cleanup

* More cleanup

* Test dashes in property names

* More cleanup
