* Accept new baselines

* Address CR feedback
* Fix parameter list length check
* Accept API baseline changes
* Add @readonly
The rule for @readonly on this-assignments in the constructor is wrong.
See failing tests.
* In-progress
Add ctor function test
Add some notes and rename variable
* Done except for cleanup and fix 1 bug
* Fix last test and clean up
* Ignore @private on constructor functions
This was incorrect in the best of circumstances and caused a crash when
the parent of the function had no symbol, because the accessibility
check assumed it was operating on a constructor and that the parent was
always the containing class.
* Non-constructors are always accessible
Previously, all function-like kinds were accessible, which includes
constructors. This was wrong.
It was previously not populated correctly if preserveSymlinks with useSourceOfProjectReference was true,
in that case if module was resolved to symlink and we deduced it refers to source of project reference we want to set "resolvedFileName" correctly
otherwise it results in incorrect module not found errors.
* Add @private/@protected/@public test
* Fix @declaration
* draft abstraction + one usage
* Fill in necessary parsing etc
* make general getEffectiveModifierFlags
move to utilities, make the right things call it
* reorder public/private/protected
* JS declaration emit works with @public/@private/@protected
* revert unneeded/incorrect changes
* Update baselines and skip @public/etc when parsing
1. Update the API baselines with the new functions.
2. Do not check for @public/etc during parsing, because parent pointers
aren't set, so non-local tags will be missed; this wrong answer will
then be cached.
* Parser: don't call hasModifier(s) anymore.
Then move jsdoc modifier tag checks into getModifierFlagsNoCache where
they should be. The jsdoc checks are skipped when the parent is
undefined. There are 3 cases when this can happen:
1. The code is in the parser (or a few places in the binder, notably
declareSymbol of module.exports assignments).
2. The node is a source file.
3. The node is synthetic, which I assume to be from the transforms.
It is fine to call getModifierFlags in cases (2) and (3). It is not fine
for (1), so I removed these calls and replaced them with simple
iteration over the modifiers. Worth noting: Ron's uniform node construction
PR removes these calls anyway; this PR just does it early.
* Fix constructor emit
1. Emit protected for protected, which I missed earlier.
2. Emit a constructor, not a property named "constructor".
3. Split declaration emit tests out so that errors are properly reported
there.
* Add tests for noEmitOnError
* Do not write files directly from builder when noEmitOnError is true
Fixes#34823
* make linter happy
* Instead of generating output in memory, check errors before doing the emit in case of noEmitOnError
Top-level this-assignments do not support computed properties. But the
binder forgets to check for computed properties and tries to bind them
normally. This hits a helpful assert.
This change stop binding this-properties with computed properties at the
top-level. There's nothing sensible we could do with them; we're unable
to late-bind entries to the global scope or to modules.

Test for #25460
* Dont store fileName on text storage
* Store root file names in the root file map to reflect their name

* Correct the name of source file as we query it (eg. it could be same source file returned in old program with different casing on case insensitive file name)
* More tests
* Refactoring
* Cache bind And check diagnostics and always get program diagnostics from the program
* Another test
* Try to report conflicting file error on file instead of global diagnostics
* Create better tests for module resolution diagnostics check
* Fix lint errors
* Move most harness globals into namespaces
* Remove forward declaration from `createMapShim` and move all `Map` declarations into one file
* A small pile of more changes to get the harness transforming
* Move codefix types into services/types.ts
* Also split apart refactorProvider
* Move all meanings of DocumentHighlights into one file
* Use setter for object allocator
* Remove unneeded namespace reference
* Remove some shorthand references to nonlocal namespace variables
* Convert WatchType string enum to a structure that can be merged across modules
* Rename harness to harnessIO
* Move accidental globals into namespace
* Remove unused globals
* Suppress lints - these qualifiers are needed for the migration to go smoothly
* Hide global declaration
Type-argument defaulting is handled elsewhere in the compiler.
This is a small drive-by improvement, so I didn't change the handling of
'array' or 'promise'; they still manually create `any[]` and
`Promise<any>`, respectively.
* Remove redundant checker functions, use patterns more friendly to modules
* Also use a helper for localizedDiagnosticMessages
* Move types into same file as consts
* Accept slightly changed api baseline
* Whitespace!
It's also defined in `corePublic.ts` - there's no errors because they're (almost) identical and merge (creating a redundant overload for `push`). Ironically, while this definition was internal, the other is public (and more complete).
When using `{import('./b').FOO}` which is defined as a string literal,
`valueType` doesn't have a `symbol`. Leave it for the fallback value
for now.
This was exposed in 8223c0752.
Fixes#34869.
* When calculating spreads, merge empty object into nonempty object to produce partial object to reduce complexity
* Actually accept remainder of baselines
* Limit simplification to single prop or partial types
* Normalize type references before relating them in isRelatedTo
* Add comments
* Accept new baselines
* Add regression tests
* Accept new baselines
* Use aliases when available in error reporting
* Accept new baselines
* Emit defineProperty calls before param prop assignments
Note that I restricted this to --useDefineForClassFields is true.
Nothing changes when it's off. I think this is the correct fix for a
patch release.
However, in principal there's nothing wrong with moving parameter
property initialisation after property declaration initialisation. It
would be Extremely Bad and Wrong to rely on this working:
```ts
class C {
p = this.q // what is q?
constructor(public q: number) { }
}
```
But today it does, and probably somebody relies on it without knowing.
* Put parameter property initialiser into defineProperty's value
* Combine ES5/ESNext into one test
* useDefineForClassFields skips emit of ambient properties
Previously:
```ts
class C {
declare p
}
```
would incorrectly emit
```js
class C {
constructor() {
Object.defineProperty(this, "p", {
enumerable: true,
configurable: true,
writable: true,
value: void 0
});
}
}
```
when useDefineForClassFields was turned on (for targets <ESNext).
* Fix bug for ESNext as well
This moves the check earlier in the pipeline.
* update baselines
* Fix up quotation marks in error messages in JavaScript files.
* Accepted baselines.
* Typescript -> TypeScript
* Accepted baselines.
* Migrate syntactic diagnostics tests to baselining tests.
* Accepted baselines.
* Update diagnosticMessages.json
* Removed markers.
* Add ability to baseline both semantic and syntactic diagnostics.
* Fix up broken diagnostics when using a server LS.
* Accepted baselines.
* Lints.
* Fake up sourcefile objects in the tsserver session client instead.
* Fewer allocations.
Also, drop the other cases where they were ignored, since they're
forbidden in enums, and the others are fine wrt the comment that was
there.
Fixes#34892
* Add inference priority level for conditional types in contravariant positions
* Accept new API baselines
* Add regression tests
* Accept new baselines
