This allows us to differentiate symbols from the system (e.g. system
includes or sysroot) differently than symbols defined in the user's
project, which can be used by editors to display them differently.
This is currently based on `FileCharacteristic`, but we can
consider alternatives such as `Sysroot` and file paths in the future.

This change makes dependentName a modifier, rather than a token type.
It can be combined with:
- type (new, standard) - this combination replaces dependentType like T::typename Foo
- unknown (new, nonstandard) - for general dependent names
- Field, etc - when the name is dependent but we heuristically resolve it
While here, fix cases where template-template-parameter cases were
incorrectly flagged as type-dependent.
And the merging of modifiers when resolving conflicts accidentally
happens to work around a bug that showed up in a test.
The behavior observed through the pre-standard protocol should be mostly
unchanged (it'll see the bugfixes only). This is done in a somehat
fragile way but it's not expected to live long.

These allow (function-) local variables to be distinguished, but also a
bunch more cases.
It's not quite independent with existing information (e.g. the
field/variable distinction is redundant if you have class-scope + static
attributes) but I don't think this is terribly important.
Depends on D77811

- Infrastructure to support modifiers (protocol etc)
- standard modifiers:
- declaration (but no definition, yet)
- deprecated
- readonly (based on a fairly fuzzy const checking)
- static (for class members and locals, but *not* file-scope things!)
- abstract (for C++ classes, and pure-virtual methods)
- nonstandard modifier:
- deduced (on "auto" whose Kind is Class etc)
Happy to drop this if it's controversial at all.
- While here, update sample tweak to use our internal names, in
anticipation of theia TM scopes going away.
This addresses some of the goals of D77702, but leaves some things undone.
Mostly because I think these will want some discussion.
- no split between dependent type/name.
(We may want to model this as a modifier, type+dependent vs ???+dependent)
- no split between primitive/typedef.
(Is introducing a nonstandard kind is worth this distinction?)
- no nonstandard local attribute
This probably makes sense, I'm wondering if we want others and how
they fit together.
There's one minor regression in explicit template specialization declarations
due to a latent bug in findExplicitReferences, but fixing it after seems OK.

Currently some clients watch for CDB changes and restart clangd, now that we
can reload compile_commands.json ourselves this is counterproductive.
The capability allows this behavior to be phased out.
This is going to be a mild regression, as we do not actually watch for files on
disk and so new diagnostics need to wait until a rebuild is requested e.g. due
to file change (and the internal caches have expired).
However this is still a better tradeoff (and if it's important, we can request
the client to watch files for us in the future).

This is a mass-market version of the "dump AST" tweak we have behind
-hidden-features.
I think in this friendlier form it'll be useful for people outside clang
developers, which would justify making it a real feature.
It could be useful as a step towards lightweight clang-AST tooling in clangd
itself (like matcher-based search).
Advantages over the tweak:
- simplified information makes it more accessible, likely somewhat useful
without learning too much clang internals
- can be shown in a tree view
- structured information gives some options for presentation (e.g.
icon + two text colors + tooltip in vscode)
- clickable nodes jump to the corresponding code
Disadvantages:
- a bunch of code to handle different node types
- likely missing some important info vs dump-ast due to brevity/oversight
- may end up chasing/maintaining support for the long tail of nodes

Summary:
Caveats:
- only works when the header is changed in the editor and the editor provides
the notification
- we revalidate preambles for all open files (stat all their headers) rather
than taking advantage of the fact that we know which file changed.
This is much simpler!

Summary:
This returns incremental highlights as a set of edits against the
previous highlights.
Server-side, we compute the full set of highlights, this just saves
wire-format size.
For now, the diff used is trivial: everything from the first change to
the last change is sent as a single edit.
The wire format is grungy - the replacement offset/length refer to
positions in the encoded array instead of the logical list of tokens.
We use token-oriented structs and translating to LSP forms when serializing.
This departs from LSP (but is consistent with semanticTokens today).
Tested in VSCode insiders (with a patched client to enable experimental
features).

This reverts commit 079ef783dd.
The revert describes a test failure without details, after offline
discussion this in in a private/unsupported build system and doesn't
seem to reflect a real upstream bug.
This reverts commit d6417f5584. The tests
depend on builtin headers, which is not intentionally supported in
clangd tests; these tests are broken in some build environments.
Summary:
This adds an implementation for the "textDocument/documentLink" LSP request.
It returns links for all `#include` directives to the resolved target files.
Fixes https://github.com/clangd/clangd/issues/217.

Summary:
This adds semantic selection to the LSP Server.
Adds support for serialization of input request and the output reply.
Also adds regression tests for the feature.
Currently we do not support multi cursor.The LSP Server only accepts single position in the request as opposed to many position in the spec.

Summary:
The existing implementation (which triggers on }) is fairly simple and
has flaws:
- doesn't trigger frequently/regularly enough (particularly in editors that type the }
for you)
- often reformats too much code around the edit
- has jarring cases that I don't have clear ideas for fixing
This implementation is designed to trigger on newline, which feels to me more
intuitive than } or ;.
It does have allow for reformatting after other characters - it has a
basic behavior and a model for adding specialized behavior for
particular characters. But at least initially I'd stick to advertising
\n in the capabilities.
This also handles comment splitting: when you insert a line break inside
a line comment, it will make the new line into an aligned line comment.
Working on tests, but want people to patch it in and try it - it's hard to
see if "feel" is right purely by looking at a test.

Summary:
Motivation:
- this layout is a pain to work with
- without a common root, it's painful to express things like "disable clangd" (D61122)
- CMake/lit configs are a maintenance hazard, and the more the one-off hacks
for various tools are entangled, the more we see apathy and non-ownership.
This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.
(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).
Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.
