* Switches from never allowing semantic highlight on JS to only doing it if we have a valid source file

* Revert to just dropping the if statement
* Test showing the moduleResolutionCache reset issue with tsc --b --w
* Fix incorrect usage of ownMap by making it function returning ownMap instead of constant value
* 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.
* address PR comments
PR #42556 was a nice optimization that dramatically sped up comparisons of discriminated unions. Unfortunately, the cost of determining whether a union is discriminated can be prohibitively high. In particular, an internal team with a very large repo saw their type count double and their memory usage increase from 6GB to 9GB, breaking their build. This changes splits the difference by not trying to compute the property types of intersection types - a notoriously slow operation.

Fixes#43909
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.

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

The second test actually requires node types

The two simple fixes, in arity error reporting, are in, and the

JSDoc typedefs don't actually have hosts, because they're not
semantically attached to a declaration. However, the parser still
attaches them to some declaration (or statement), but that declaration
is not related to the typedef.
Previously, delayedBindJSDocTypedefTag used getJSDocHost to walk past
the unrelated declaration, but #41858 correctly started categorising
typedefs as unattached, with no host, so the binder began falling
back to file scope.
The path to skip the unrelated declaration is always the same, though, so this
PR uses `typeAlias.parent.parent` instead of `getJSDocHost(typeAlias)`.
* Consider identical instances of the same symbol equivalent when creating union and intersection properties
* Also copy over mapper and type (if available) on cloned symbols

This should only happen in JS files, however, and there needs to be some
conditional handling of jsdoc on statements that can't have jsdoc in TS
files.
* Finish change
* Add test

The test is pretty good, the scribbles are actually cleanup from last
PR, although they break some tests.

`fs.statSync` throws `ENOENT` if there is a symlink to a nonexistent
target. This can be avoided by checking that the entry exists before
using it.
(This is annoying when editing tests in Emacs, since it keeps lock files
for modified-but-unsaved files, which are `.#foo` symlinks to a
nonexistent target.)
* Specified diagnostic for CLI flags missing a required --build
* Switched to an alternateMode member
* Added --build-incompatible flags too
* Small fixups to remove a hardcoding

* Allow redeclaring CommonJS alias with initial undefined
This allows us to read our own output, plus the times when people
manually write exactly the same pattern.
Fixes#40555
* Use control flow to type commonjs exports
1. Could probably use a *lot* more tests.
2. getTypeOfAlias redoes some work from resolveAlias because it needs to
not resolve the alias completely, just to its export.
* fix lint, improve jsdoc
* Add tests, improve+fix control flow
1. Update the module.exports test to match the exports ones.
2. Add a test of evolving commonjs type.
3. Add a test of assignment as last statement.
(1) exposed a bug that required a better synthetic reference. (3)
exposed a bug that was most easily fixed by giving source files a
`endFlowNode` like functions and setting it in the binder.
* fix lint

* Exclude keyof from constraint variance tracking
* Extra test case
* Always subtitute on type parameter types

Intead of unconditionally retrieving the last error and attaching a
related span, `parseErrorAt` and friends now return the last error and
return `false` when there is none.
Also make one more place use parseExpectedMatchingBrackets that I missed
last time.

...when missing `program.redirectTargetsMap` info. This assertion fails
in the added test case -- looks like there is no entry in
`program.redirectTargetsMap` when it comes from a file that is no in the
project. So in this case don't follow the (missing) info, and instead
drop the highlight.

A misbehaved client can sometimes cause the server to reach
`deleteDeclaration` with the SourceFile, and it will crash due to no
`node.parent`. I couldn't find a good way to create a test for it, but
I could trigger it manually by having a file with just a `,`, and
sending an explicit `getCodeFixes` command to the server with
`errorCodes: [6133]`.
Do three things to improve this:
1. `textChanges.ts`: if we get here with the root node, delete it
instead of failing.
2. `fixUnusedIdentifier.ts`: check that we don't `delete` a node that is
the whole source file, so the error is more focused (should have more
similar failure stacks).
3. `session.ts`: when there was any failure in `getCodeFixes`, check if
the input had a diag code that does not appear in the requested text
range, and throw an error saying that the failure is probably a
result of a bad request.
Closes#33726 (probably not fixing it, but making it easier to find the
cause)
* Extra tests in preparation for lazy signature making sure the original intent of test is maintained
* Whenver we cant use state delay signature calculation and use source file version as signature
* Incremental correctness checks
* Retain old behavior in compile on save by disabling use of file version as signature in when state is not reused
* Revert "Revert "Editor support for link tag (#41877)" (#43302)"
This reverts commit 451d4354b9.
* Fix parsing @link at end of comment
* Parse comments as string when no @link occurs
* fix lint
