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
* Editorial feedback
* Add jsdoc to if statements
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
* Test + Initial scribbles
The test is pretty good, the scribbles are actually cleanup from last

`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
* Switched to ||= factories
* Not a function
* I think I get it now

* Added error if a private identifier is used in a static a initializer if target:ESNext and useDefineForClassFields:false.
* Added test for new useDefineForClassFields default and error message.
* Fixed tests after changing the default of useDefineForClassFields to true for target esnext
* Fixed code review suggestions.
* Updated error message.
* Added missing static check for the containing property. Fixed other code review issues.
* 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
* Test that fails because of change in scriptKind of untitled file
* buckets are keyed with DocumentRegistryBucketKey
* Use scriptKind in document Registry to distinguish between files

* Exclude keyof from constraint variance tracking
* Extra test case
* Always subtitute on type parameter types
* Only issue matching token errors on non-dupe locations
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

* Add comment
* Initial scribbles
* Compiles but provides spans instead of location pairs
Probably need to fork the services/server types and provide a conversion
with Session.toFileSpan. Not sure where to put the conversion.
* Switch to DocumentSpan
In theory this is already better supported, but not sure practise bears
that out.
* Builds w/protocol types + conversions
* cleanup:better names and scrub TODOs
* fix test harness too
* Misc
1. Simplify protocol after talking to @mjbvz.
2. Add more tests.
3. Initial notes about where to add parsing.
* Parse and store links in the compiler
The text of the link is still stored in the comment text, but that's now
kept in an object instead of just a string. Each link has the parse for
the entity reference, if there is one.
Needs lots more tests -- this just makes all the existing jsdoc tests
pass.
* more tests and some fixes
* Fix other failing tests
* fix bad merge
* polish parser
* improve names and array types
* slight tweaks
* remove some done TODOs
* more tests + resulting fixes

* Add span for link.name in language service/protocol
* Make checker optional in getJSDocTags
Also change to JSDocCommentText from JSDocCommentComment
* Use getTokenValue instead of getTokenText

* Add missing support for top-level links
The language service and protocol were missing support for top-level
links. This commit adds that plumbing.
* add string back to comment type in node constructors
* Full parse of link tags and jsdoc comment text
- Doesn't pass fourslash yet, I'm going to switch to baselines for
failures there.
- Still needs some work on the protocol to convert file+offset to
file+line+offset.

Instead of upgrading them to displayparts.
* Real server tests
* Disambiguate {@link} and @param x {type}
They are ambiguous; previously the parser preferred the type
interpretation, but will now look ahead and parse links instead when the
prefix is `{@link`.

* update API baseline
* Address PR comments
1. Add a cross-file goto-def test.
2. Switch from per-message args to UserPreference.

This was caused by the fact that getTypeWithFacts(resultType, TypeFacts.NEUndefinedOrNull) will return never both if resultType was already never and if resultType does not contain undefined or null. In the latter case returning the declaring type is correct, in the former case this causes something narrowed to never to still be typed as the original declared type.
Fixes#38070
When the originating definition was of the form
```js
module.exports.foo = expr
```
we were incorrectly trying to call `resolveName` on just the `foo` portion to get the "local" symbol, which simply failed to resolve (or would have resolved to the wrong thing), but for this form, the local symbol is just the containing property access expression
* Baseline readable buildinfo

Previously, when getting jsdoc for signatures, the services layer would
get the jsdoc tags for the base symbol of a signature if it was
present. This is fine except when the base was overloaded. In that case,
the multiple signatures of the overload would all contribute jsdoc,
which is not correct.
A more correct fix would be to resolve overloads to the base, but
the compiler doesn't have this capability and adding it or jury-rigging
it seems like it would be complex, inappropriate for a fix to ship in a
patch version.

* Add another example from an issue, albeit slightly modified
* Fix newlines, add test from DT
* Interior remodelling
* Improve @template lookup and resilience
1. @template parsing may produce a template tag with a type parameter
whose name is the missing identifier. These tags should be skipped
in the checker because they receive an error in the parser.
2. The fix in #37819 was incorrect; there's no such thing as a type
parameter declared on a variable declaration. Instead, there needs to be a type
parameter declared on a jsdoc comment, because that's the scope for tags
like `@return` and `@typedef`.
There are 3 tests because either fix (1) and (2) fix the first test's
failure, but both are required to fix the last two tests' failures.

Changes:
1. Change BCP47LanguageTag to UnicodeBCP47LocaleIdentifier: Those mean 2

doesn't. It also allows grandfathered locales and UTS35 doesn't.
2. Combine RelativeTimeFormat interface and const declaration into a
single class. The old way of declaring as `interface` & `const` permits
calling `Intl.RelativeTimeFormat` without `new` which is no longer
possible after `Intl.DateTimeFormat` & `Intl.NumberFormat`. The spec
explicitly forbids it in

Intl.RelativeTimeFormat is also extensible per spec. This is closer to a
`class` than the current declaration.

* No did-you-mean-to-call error on casts
I chose to do the ad-hoc check rather than yet another tree walk.
1. It's faster to run and easier to read.
2. This error came from looking at real code. It happened twice, so I
think the best estimate for other uses that happened zero times is in
fact zero.
3. I couldn't think of other places to put the cast, given the
restrictions on `testedNode` just before the new code.
