Previously, property assignments with `void 0` initialisers were treated
like any other values. But this causes us to choke when checking our own
commonjs emit. This is something that happens by mistake a fair amount,
so this PR goes back to treating these assignments as normal
assignments.
This should allow us to check our own emit in loose cases without
harming other code bases, since `void 0` is rarely written by hand.
Note that other errors still happen: noImplicitAny forbids
accessing undeclared properties on object literals, and strictNullChecks
forbids assigning `undefined` to properties with a different type.
However, this change is enough to unblock compilation with
`strictNullChecks: false`.

* Update function/constructor-type factories
* Remove treeStateObserver

* Fix base factory used for source file updates
* Update test baseline due to merge from master
* Rename factory methods to be more consistent (#39058)
Neither `x[0]` nor `x[(0)]` should be dynamic names. Previously, the
latter was because `isDynamicName` didn't skip parentheses.
Since the binder treats dynamic names in property assignments as
assignment declarations, this incorrectly tried to create a binding for
expressions like `x[(0)] = 1`.
This caused an assert because `x[(0)]` would not take the dynamic name
code path during binding (`hasDynamicName` returned false), but the
normal code path for static names.
* Allowed comment directives to be multiline
* Added tests, and perhaps fixed a test runner bug?
* I think it's going to need a consistent variable to loop over
* Used dynamically computed indexes in verifies
* Added multiline tests

* Adds support for looking up past Blocks in expando objects
* Adds JS tests to validate the JS parsing also works
* Get the top level block expando tests green
* Fix crash for private identifier in expando assignments
It does this by disallowing private identifiers from expando assignments
entirely. I haven't thought of a scenario where they make sense, but I
haven't thought about it exhaustively either.
Fixes#37356
* Update baselines
I think the new error is probably better. It's certainly different!
* Accept change
* Accept the huge set of ever so slightly changed baselines
* Update return type logic to only reuse nodes if original nodes share scope with current node, like property types, only reuse nodes if symbols referened are acessible, reuse nodes for property signatures, too
* Only reuse nodes when a context is provided (otherwise identifier printback may fail)
* Only track symbol if symbol is found and no error is recorded
* Fix type parameter reuse lookup
* Forbid cjs module.exports references in retained nodes
* Adjust check for cjs export references to not include bad module type in output
* Add symbol to all identifiers we see in existing nodes for quickinfo
* Accept fourslash baseline updates
* Accept slightly updated baseline post-merge
* Do not copy original nodes for error types, replace empty type references with any

* Added @ts-expect-error to @ts-ignore directives
Similar to `// @ts-ignore`, but will itself cause a new error diagnostic if it does not cause an existing diagnostic to be ignored.
Technical summary:
1. The scanner will now keep track of `CommentDirective`s it comes across: both `@ts-expect-error` and `@ts-ignore`
2. During type checking, the program will turn those directives into a map keying them by line number
3. For each diagnostic, if it's preceded by a directive, that directive is marked as "used"
4. All `@ts-expect-error` directives not marked as used generate a new diagnostic error
* Renamed to getDiagnosticsWithPrecedingDirectives per suggestion
* Added JSDoc comment I thought I did already

Use `emit()` for writing `questionDotToken`, leading to properly calling
the emit hooks (which `emitTokenWithComment` doesn't) and printing the
comments. This fixes#35372 by calling its hooks to set the `.__pos`
and `.__end` fields.
Also, remove `getDotOrQuestionDotToken` which was used only here --
mainly because it seems likely to encourage misusing the
`questionDotToken` again.
Also, fix a bunch of `visitor` -> `tokenVisiton` calls in
`visitorPublic.ts`.
* Remove bogus @implements errors
Make the search for the actual host more comprehensive by reusing the
code that previously only searched for functions. I don't know what to
call this function now, since the old name wasn't accurate either.
* undo gratuitous name change
* Improve name and make calling more uniform
It's slightly less efficient but I think worthwhile for readability.
* Adding support for @implements.
* Fixed code review issues for @implements, added some more tests.
* Fixed declaration emit for @interface
* Improved getImplementsTypes to not cache the results since it is only used once.
* Removed unnecessary checks from getImplementsTypes
