... with the "usedAsMutableReference" semantic token modifier.
It's quite unusual to declare the index parameter of a subscript
operator as a non-const reference type, but arguably that makes it even
more helpful to be aware of it when working with such code.

Fixes https://github.com/clangd/clangd/issues/1132
where clangd's semantic highlighting is missing for symbols of a template
specialization definition. It turns out the visitor didn't traverse the
base classes of Class/Var##TemplateSpecializationDecl, i.e.
CXXRecordDecl/VarDecl. This patch adds them back as what is done in
DEF_TRAVERSE_TMPL_PART_SPEC_DECL.

We could add hover information / xrefs, but it's very unlikely

Objective-C lets you use the `self.prop` syntax as sugar for both
`[self prop]` and `[self setProp:]`, but clangd previously did not
provide a semantic token for `prop`.
Now, we provide a semantic token, treating it like a normal property
except it's backed by a `ObjCMethodDecl` instead of a
`ObjCPropertyDecl`.

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.

Treat them just like we do for properties - as a `property` semantic

- highlight references to protocols in class/protocol/extension decls
- support multi-token selector highlights in semantic + xref highlights
(method calls and declarations only)
- In `@interface I(C)`, I now references the interface and C the category
- highlight uses of interfaces as types
- added semantic highlightings of protocol names (as "interface") and
category names (as "namespace").
These are both standard kinds, maybe "extension" will be standardized...
- highlight `auto` as "class" when it resolves to an ObjC pointer
- don't highlight `self` as a variable even though the AST models it as one
Not fixed: uses of protocols in type names (needs some refactoring of
unrelated code first)
Differential Revision: https://reviews.llvm.org/D97617
This is obsoleted by the standard semanticTokens request family.
As well as the protocol details, this allows us to remove a bunch of plumbing
around pushing highlights to clients.
This should not land until the new protocol has feature parity, see D77702.

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.

- 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.

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).

Summary:
This ties to an LSP feature (diagnostic versioning) but really a lot
of the value is in being able to log what's happening with file versions
and queues more descriptively and clearly.
As such it's fairly invasive, for a logging patch :-\
Key decisions:
- at the LSP layer, we don't reqire the client to provide versions (LSP
makes it mandatory but we never enforced it). If not provided,
versions start at 0 and increment. DraftStore handles this.
- don't propagate magically using contexts, but rather manually:
addDocument -> ParseInputs -> (ParsedAST, Preamble, various callbacks)
Context-propagation would hide the versions from ClangdServer, which
would make producing good log messages hard
- within ClangdServer, treat versions as opaque and unordered.
std::string is a convenient type for this, and allows richer versions
for embedders. They're "mandatory" but "null" is a reasonable default.

This has the same behavior as converting std::string_view to
std::string. This is an expensive conversion, so explicit conversions
are helpful for avoiding unneccessary string copies.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
This reflects its current function better and avoids confusion with clang::DiagnosticConsumer.
The old name/constructor is left around temporarily for compatibility.

Summary:
The historic behavior of TestTU is to gather diagnostics and otherwise ignore
them. So if a test has a syntax error, and doesn't assert diagnostics, it
silently misbehaves.
This can be annoying when developing tests, as evidenced by various tests
gaining "assert no diagnostics" where that's not really the point of the test.
This patch aims to make that default behavior. For the first error
(not warning), TestTU will call ADD_FAILURE().
This can be suppressed with a comment containing "error-ok". For now that will
suppress any errors in the TU. We can make this stricter later -verify style.
(-verify itself is hard to reuse because of DiagnosticConsumer interfaces...)
A magic-comment was chosen over a TestTU option because of table-driven tests.
In addition to the behavior change, this patch:
- adds //error-ok where we're knowingly testing invalid code
(e.g. for diagnostics, crash-resilience, or token-level tests)
- fixes a bunch of errors in the checked-in tests, mostly trivial (missing ;)
- removes a bunch of now-redundant instances of "assert no diagnostics"

This reverts commit 7f93cb6228.
The assertion at RecursiveASTVisitor.h:1169 fails when passed a TypeLocNode.
Not sure if the correct fix is to use getTypeLocClass or something else.
Summary:
To keep the logic of finding locations of interesting AST nodes in one
place.
The advantage is better coverage of various AST nodes, both now and in
the future: as new nodes get added to `findExplicitReferences`, semantic
highlighting will automatically pick them up.
The drawback of this change is that we have to traverse declarations
inside our file twice in order to highlight dependent names, 'auto'
and 'decltype'. Hopefully, this should not affect the actual latency
too much, most time should be spent in building the AST and not
traversing it.
