Eli Barzilay f47ddbc3b0 Fix bad line number assertion in ScriptInfo.positionToLineOffset
This is the line number side of ecddf8468f (from #21924, fixing #21818).
But the code is slightly improved for both cases: instead of testing
that `leaf` is defined, check whether `lineCount` is zero, and if it is,
return `〈1,0〉` for the one-based line and zero-based column numbers.
(The requirement of `lineCount > 0` is also seen in the fact
that `lineNumberToInfo` expects a "*One*BasedLine" argument.)

I've stared at this code way too much, since I think that there is
something more fundamentally wrong here.  E.g., `EditWalker` only
`push`es to `startPath` but never pops even a `children`-less node that
is left after deleting the whole contents.  But I can't figure out the
overall structure, which is also why the test that I added is not
great (see the comment there; also, #21924 is dealing with the same
problem and didn't add a test).

Fixes #44518.

Avoid the assumption that there are always include patterns: when there
are none (and therefore the renamed file didn't match anyway), just skip
the test for added include.

Also change the code to use `return` to make it flatter.

(Also get rid of a redundant type.)

Eli Barzilay fad9122872 services/utilities/getMeaningFromLocation(): fix w/ export specifiers
Fixes 44167, but also two other things:

* On an import/export, climb upto the declaration, and use
  `SemanticMeaning.Type` if it's a `type` only import/export.

* Add a `test.rangesInFile()` to fourslash, so it is easy to do multiple
  files in one test without an awkward filter (which was done in one
  more test).

Issue "Cannot find name did-you-mean" errors as suggestions in plain JS (#44271)
* Always issue cannot find name did-you-mean error

This PR issues "cannot find ${name}, did you mean ${name}" errors for
identifiers and propery access expressions in JS files *without*
`// @ts-check` and without `// @ts-nocheck`. This brings some benefits of
Typescript's binder to all Javascript users, even those who haven't
opted into Typescript checking.

```js
export var inModule = 1
inmodule.toFixed() // errors on exports

function f() {
    var locals = 2
    locale.toFixed() // errors on locals
}
var object = {
    spaaace: 3
}
object.spaaaace // error on read
object.spaace = 2 // error on write
object.fresh = 12 // OK, no spelling correction to offer
```

To disable the errors, add `// @ts-nocheck` to the file. To get the
normal checkJs experience, add `// @ts-check`.

== Why This Works ==

In a word: precision. This change has low recall &mdash; it misses lots
of correct errors that would be nice to show &mdash; but it has high
precision: almost all the errors it shows are correct. And they come
with a suggested correction.

Here are the ingredients:

1. For unchecked JS files, the compiler suppresses all errors except
two did-you-mean name resolution errors.
2. Did-you-mean spelling correction is already tuned for high
precision/low recall, and doesn't show many bogus errors even in JS.
3. For identifiers, the error is suppressed for suggestions from global files.
These are often DOM feature detection, for example.
4. For property accesses, the error is suppressed for suggestions from
other files, for the same reason.
5. For property accesses, the error is suppressed for `this` property
accesses because the compiler doesn't understand JS constructor
functions well enough.
In particular, it doesn't understand any inheritance patterns.

== Work Remaining ==

1. Code cleanup.
2. Fix a couple of failures in existing tests.
3. Suppress errors on property access suggestions from large objects.
4. Combine (3) and (4) above to suppress errors on suggestions from other, global files.
5. A little more testing on random files to make sure that precision
is good there too.
6. Have people from the regular Code editor meeting test the code and
suggest ideas.

* all (most?) tests pass

* NOW they all pass

* add tonnes of semi-colons

* restore this.x check+add a test case

* make ts-ignore/no-check codefix work in unchecked js

* Issues errors only in the language service

* add a few more tests

* fix incorrect parentheses

* More cleanup in program.ts

* Improve readability of isExcludedJSError

* make diff in program.ts smaller via closure

* Switch unchecked JS did-you-mean to suggestion

Instead of selectively letting errors through.

* undo more missed changes

* disallow ignoring suggestions

* Issue different messages for plain JS than others

Straw text for the messages, I just changed the modals to avoid name
collisions.

Eli Barzilay 5be0d7156d Fix bug due to sharing of .type.members
Function extraction failed when using two identical `TypeLiteral`s ---
the problem is that the parameters' `.type.members` are shared in their
two occurences in the resulting code, and when the formatter bangs
position properties on the second, it's actually changing the first too.

* `typeToAutoImportableTypeNode`: wrap in `getSynthesizedDeepClone` to
  avoid the offeding sharing.

* `getSynthesizedDeepCloneWorker`: add optional nodes/token visitors so
  it doesn't skip cloning the above.

* A few very minor tweaks which I saw when tracing this (comment update,
  two `!`s).

Make handleDtsMayChangeOf void-returning (#44322)
* Make handleDtsMayChangeOf void-returning

Right now, it always returns false.  This seems important, since
otherwise it would stop graph traversals prematurely.  It took me a
while to figure that out though and I thought it might be clearer if it
were simply void-returning.

I've kept the behavior the same, except in
`forEachReferencingModulesOfExportOfAffectedFile`, where it seemed like
never enqueueing new references was a mistake.

* Make forEachFileAndExportsOfFile void-returning

As far as I can tell, it could only return `false`.

Add unqualified JSDoc member references (#44202)
* Add unqualified JSDoc member references

This allows unqualified references like:

```ts
class Zero {
 /** @param buddy Must be {@link D_HORSE} or {@link D_DOG}. */
 deploy(buddy: number) { }
 static D_HORSE = 1
 static D_DOG = 2
}
```

I surveyed @see and @link again to estimate how common this is. I found
a little over 200 uses, which is around 2%. Sorted by frequency, this
*is* the next feature on the list, along with the `module:` prefix.
So I think this is about the right point to stop adding code.

In this case, however, I liked most of the uses -- there were a lot
of deprecated functions that referenced a function just below, where it
would be wordy to qualify the name, but the reader would benefit from a
link.

Note that unqualified references do *not* work inside type or object
literals. The code I ended up with is quite complicated and I didn't
observe any uses in the wild.

Avoid calling replace in normalizeSlashes when it would do nothing (#44100)
* Make normalizeSlashes a no-op there are no bad slashes

On Windows, there will probably be a negligible slowdown, iterating over
the pre-slash prefix of each unnormalized path (though we might come out
ahead if paths are normalized more than once).

On *nix, this saves work - 1.8s -> 0.4s in the project I'm
investigating.

* Reuse already-computed index

Add jsdoc member names: Class#method (#44150)
* Everything mostly works

A couple of mixed, nested references don't work yet.
The scanner+parser interaction is wrong, the parser consumes one too
many spaces, and the checker+services code needs a little cleanup.

* Cleanup

1. I decided that correctly parsing a#b.c, an entity name containing an
instance reference, is not worth the work.
2. I made the scanner, at least the jsdoc part, emit a # token, and
provided a reScanPrivateIdentifier in order to convert #a to # a.
3. I cleaned up the code in the checker.
2. Unrelated: I added a missing space in linkPart display.

Eli Barzilay 5ca7983ebe Fix the code that checks for variadic signatures
This code looks strange, like there's a typo in it (eg, using `lists` in
the `parameterList` loop, etc) -- so I also refactored it a bit to look
more intentional.  The new format makes it clearer that `lists` is
checked once *outside* the loop, as well as the role of
`hasEffectiveRestParameter`.

The actual bug fix is checking `pList.length` in the new `isVariadic()`.

Fixes 41059.

Eli Barzilay 0454ae4720 Loosen up the first argument type for String.raw
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.

Improve errors for incorrectly nested export default (#43967)
* 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.

Fix perf regression from #42556 (#43949)
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.

Displayparts resolves non-values in link tags (#43903)
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.

getExternalModuleMember:always resolve alias of moduleSymbol (#43718)
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.

Skip up-to-date checks during force build (#43666)
* Skip up-to-date checks during force build

Save work by not checking timestamps or parsing the buildinfo file.
Retain correctness checks (like input file existence).

Suppress project status, which was confusing anyway.

* Print a message to indicate that --force is causing the rebuild

* Don't bother updating buildInfoChecked

* Add missing force check

Fix @typedef/@callback scope (#43682)
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)`.

Add jsdoc to all js statements (#43659)

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.
