* Fix jsdoc comment parsing initial state
Jsdoc comment parsing can be invoked in two modes:
1. top-level parsing, for comments not inside a tag.
2. tag parsing, for comment that occur after the semantic parts of a
tag.
Top-level parsing skips an initial * because it assumes that it is starting
at the very beginning of a JSDoc comment. Tag parsing does not.
The two modes are distinguished by an optional second parameter named
`margin`. When `margin` is provided, it provides an initial indent used
for comment alignment.
Previously, the check for `margin` was a truthy check `if (margin)`.
This check incorrectly treats `margin=""` the same as
`margin=undefined`.
This PR changes the check to `if (margin !== undefined)`, which
correctly treats `margin=""` the same as `margin=" "`.
* Fixes for broken tests
1. Use SawAsterisk start state.
2. @template needs to skip asterisk in addition to whitespace while
parsing type parameter names.
* undo code move
* Improve reasoning about when to create deferred type references
* Accept new baselines
* Fix minor issues
* Handle default type arguments case in isDeferredTypeReferenceNode
Exposes `hasOnlyExpressionInitializer` as a public function so users of
TypeScript compiler APIs do not have to roll their own
`HasExpressionInitializer` type guards.

* Combine 3 type-only marking function calls into one
* Add more export default tests
* Class fields w/esnext+[[Define]]:no shadow error
With useDefineForClassFields: true and ESNext target, initializer
expressions for property declarations are evaluated in the scope of
the class body and are permitted to reference parameters or local
variables of the constructor. This is different from classic
Typescript behaviour, with useDefineForClassFields: false. There,
initialisers of property declarations are evaluated in the scope of
the constructor body.
Note that when class fields are accepted in the ECMAScript
standard, the target will become that year's ES20xx
* add negative test case
* Add explanatory comment
Previously subtypes of Error extended Error, but the matching subtypes
of ErrorConstructor did not extend ErrorConstructor. The members in
es5.d.ts are identical, so there's no need except for allowing interface
merging into ErrorConstructor to affect subtypes as well.
Previously the jsdoc index signature syntax was incorrectly treated the
same as Object:
```js
/** @typedef {Object} AllowsNesting
* @property ... */
/** @typedef {Object.<string,string>} IncorrectlyAllowsNesting */
```
Fixes#34911
