Sheetal Nandi 3c67608715 When interfaces are merged, always ensure that the parent symbol of the late bound member symbol is declared symbol containing the node. 
Ensure that resolvedMembers adds the late bound symbol even when its resolved sunce lateBoundMember may or may not be added to resolved members depending on when its checked

Nathan Shively-Sanders ff959096df Fix some bad jsdoc comment indent (#30838) 
* First draft

Solves the initial problem but breaks commentCommentParsing. I also
found a couple more interesting cases.

* Add more tests and fix their bugs

* Another test case

* Some cleanup

I may try do a little more; `margin += tag.end - tag.pos` bothers me a
bit.

* More cleanup

Nathan Shively-Sanders dabf2a6af2 Always check extends clause of classes 
Even if (1) @extends is provided and (2) we're not producing
diagnostics. That's because we need to know whether the extends clause
references an imported alias.

Nathan Shively-Sanders 0b3b4ea127 Added error for class properties used within their own declaration (#29395) 
* Added error for class properties used within their own declaration

Fixes #5987.

Usages of a class property in a preceding property already gave an error, but the following doesn't yet:

```ts
class Test {
    x: number = this.x;
}
```

As with other use-before-declare checking, IIFEs are not treated as invalid uses.

* Accepted 'witness' baselines; removed unnecessary !==

* Addressed quick feedback items

* Accepted odd new baseline

* Fixed post-merge introduced lint errors

* Updated baselines again

* Relax unknown checking outside of strictNullChecks a bit

* Increase strictness on index signatures with type `unknown` so inference doesnt change surprisingly
