* Cache accessibe symbol chains, type parameter name generation
* Move signature declaration helper length approximation to start of function
* Add node result caching internal to `typeToTypeNodeHelper`
* Suggestion from PR
The [String.raw spec](https://tc39.es/ecma262/#sec-string.raw) uses just
the `raw` property of its first argument, which is a useful way of using
it in user-defined tag functions to do the work of interleaving strings
and values as well as converting the values to strings.
Fixes#43609.
* Switches from never allowing semantic highlight on JS to only doing it if we have a valid source file
* Adds a way to test and validate that an arbitrary JS file gets semantic classification results
* Revert to just dropping the if statement
* Improve errors for incorrectly nested export default
The compiler and services don't handle incorrectly nested
`export default` well right now:
```ts
export = (x,y) => {
export default { }
}
```
Asking for document highlights, find all references or quick info on
'export' or 'default' cause a crash. After the crash is fixed, the error
message is confusing and wrong: "An export assignment cannot be used outside a module."
This PR:
1. Skips document highlights for incorrectly nested export default.
2. Skips find all refs for incorrectly nested export default.
3. Switches the fallback binding for incorrectly nested export default
from Alias to Property. Neither is correct, but Property doesn't cause a
crash in alias resolution.
4. Improves the error message to reflect a post-ES module world, which
has export default and 'module' means 'ES module', not 'namespace'.
Fixes#40082 and the related bugs mentioned above.

Previously, the name resolution for link tags in displaypart generation
mistakenly required a valueDeclaration. Now it uses the first
declaration if there is no valueDeclaration, so that types and
namespaces will also resolve.
This is another instance of using valueDeclaration as "the default
declaration", which doesn't apply to types.

* Update src/services/goToDefinition.ts
Previously, getExternalModuleMember passed through its received value of
`dontResolveAlias` to every function that accepted it. That includes (1)
resolution of the module symbol and (2) resolution of the module
specifier. However, in TS, the module symbol is never an alias anyway, so
dontResolveAlias doesn't make a difference. In JS, the module symbol
*can* be an alias, and it should always be resolved. That's what this PR
does.
Fixes#43713
* Scribbles + tests
The second test actually requires node types
* Basically working
The two simple fixes, in arity error reporting, are in, and the
simplification of arity error reporting is half-done. I haven't started
on any improvements to call assignability.
* trim out too-real test case
* Finish cleanup
And reword error a little.

* Complete `constructor` keyword after property declaration.
* Fix logical errors.
* Fix for more universal situations.
* Only provide completions if property declaration is terminated.
* Simplify many logical conditions.

This diff extends the types checked by
discriminateContextualTypeByObjectMembers and
discriminateContextualTypeByJSXAttributes to also include any optional
components in the type union.
fixes#41759 although it doesn't address the better error reporting for
their last repro, which I'm not sure how to address.
