Don't build type catalog during server tracing (#43354)
Bonus: this also drops the redundant type catalog from the
non-diagnostics-producing checker.

Editor support for link tag (#41877)
* 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+fix cross-module tests

* Support `@see {@link`

Plus find-all-refs support equivalent to @see's.

* add server test

* Make comments actually part of the AST

* 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

Measure twice, slice once

* 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.

* fix lint

* Fix missing newlines in inferFromUsage codefix

* Parse jsdoc comments as text node/link array

And switch to line+character offsets in the protocol

* Fix fourslash tests

Mostly ones that can't be baselined, but I switched a couple more over
to baselines

* Improve types and documentation

* Test+fix @link emit, scrub other TODOs

* update API baselines

* test that goto-def works with @link

* Split link displaypart into 3

One for link prefix and suffix, one for link name, and one for link
text.

* update baselines

* Provide JSDocTagInfo.text: string to full clients by default

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`.

* Add explanatory comment in test

* fix location in richResponse in protocol

* update API baseline

* Address PR comments

1. Add a cross-file goto-def test.
2. Switch from per-message args to UserPreference.

* use arraysEqual from core

Fixed issue where non null assertion caused getFlowTypeOfReference to return the declared type if the type was already narrowed to never. (#35863)
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.
