Matt McCutchenandRyan Cavanaugh 6487d1ffe0 Remove the rule that replaces a union of literal types with the base type when comparing equality to a type that isn't a union of literal types. (#27588) 
type when comparing equality to a type that isn't a union of literal
types.

The rule is redundant because a primitive type is already directed-
comparable to a value of that primitive type, and it causes errors to be
missed when comparing a type parameter _constrained_ by a union of
literal types to another union of literal types.

The baseline changes look like improvements to me.

Fixes #26758.

Nathan Shively-SandersandGitHub 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

Nathan Shively-SandersandGitHub 0f598db3e5 Fixes #29524, a merged UMD-global (#30403) 
This kind of merged symbol causes crashes in two places because it's
marked BlockScoped, which makes us assume that it must be something that
is inside a SourceFile. However, block-scoped checks don't make sense
for this kind of symbol, so I exclude them by looking at the kind of
the valueDeclaration, as @mprobst suggested in the original bug.
