7954f0c947 Kick out of normalizePath if there's nothing to do (#44173)
* Kick out of normalizePath if there's nothing to do

...using `relativePathSegmentRegExp`.

Bonus: use a regex to handle "/./" to avoid splitting and joining in a
common case.

When building the compiler, for example, it looks like ~95% of arguments
to `normalizePath` do not require any normalization.

* Check normalization before and after . cleanup

* Also cleanup leading ./

14343bead8 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

086423729a 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.

* Cleanup lint + var naming

* investigate+clean up a couple of TODOs

* Fix lint in utilities.ts

* change name to JSDocMemberName

* address PR comments

89a737c871 Improve parser recovery for unclosed/mismatched JSX elements (#43780)
* First draft

Everything works, the error messages for unmatched opening elements
could still use improvement, plus there is tonnes of unused and ugly
code.

1. Make sure the parser can recover from all kinds of unclosed tags.
2. Improve the parse tree for unmatched opening tags.
3. Better errors at some point.

* Lots of cleanup

* Improve readability of construction/fix lint

* improve line-length formatting

f6303652d2 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.

1ce15a4531 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.

c9eb62fafb 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.
