and fixed a few hundred of them in all of the llvm project (note, the

- Correct nameLocation to point to the first selector fragment instead

- Do not traverse concept decl inside `AutoType`. We only traverse
declaration and definitions, not references to a declaration.
- Do not visit implicit AST node the relevant traversal mode.
- Add traversal extension points for concept requirements.
- Renamed `TraverseConceptReference` to mark as helper to share
the code. Having an extension point there seems confusing given that
there are many concept refences in the AST that do not call the
helper. Those are `AutoType`, `AutoTypeLoc` and constraint requirements.
Only clangd code requires an update.
There are no use-cases for concept requirement traversals yet, but
I added them in the earlier version of the patch and decided to keep
them for completeness.

Add support for concepts and requires expression in the clang index.
Genarate USRs for concepts.
Also change how `RecursiveASTVisitor` handles return type requirement in
requires expressions. The new code unpacks the synthetic template parameter
list used for storing the actual expression. This simplifies
implementation of the indexing. No code seems to depend on the original
traversal anyway and the synthesized template parameter list is easily
accessible from inside the requires expression if needed.
Add tests in the clangd codebase.

This makes hover/go-to-definition/expand-auto etc work for auto params in many
common cases.
This includes when a generic lambda is passed to a function accepting
std::function. (The tests don't use this case, it requires a lot of setup).
Note that this doesn't affect the AST of the function body itself, cause its
nodes not to be dependent, improve code completion etc.
(These sort of improvements seem possible, in a similar "if there's a single
instantiation, traverse it instead of the primary template" way).

Auto-generated patch based on clang-tidy readability-identifier-naming.
Only some manual cleanup for `extern "C"` declarations and a GTest change was required.
I'm not sure if this cleanup is actually very useful. It cleans up clang-tidy findings to the number of warnings from clang-tidy should be lower. Since it was easy to do and required only little cleanup I thought I'd upload it for discussion.
One pattern that keeps recurring: Test **matchers** are also supposed to start with a lowercase letter as per LLVM convention. However GTest naming convention for matchers start with upper case. I would propose to keep stay consistent with the GTest convention there. However that would imply a lot of `//NOLINT` throughout these files.
To re-product this patch run:
```
run-clang-tidy -checks="-*,readability-identifier-naming" -fix -format ./clang-tools-extra/clangd
```
To convert the macro names, I was using this script with some manual cleanup afterwards:

This reverts commit cc56c66f27.
Fixed a bad assertion, the target of a UsingShadowDecl must not have
*local* qualifiers, but it can be a typedef whose underlying type is qualified.
Currently there's no way to find the UsingDecl that a typeloc found its
underlying type through. Compare to DeclRefExpr::getFoundDecl().
Design decisions:
- a sugar type, as there are many contexts this type of use may appear in
- UsingType is a leaf like TypedefType, the underlying type has no TypeLoc
- not unified with UnresolvedUsingType: a single name is appealing,
but being sometimes-sugar is often fiddly.
- not unified with TypedefType: the UsingShadowDecl is not a TypedefNameDecl or
even a TypeDecl, and users think of these differently.
- does not cover other rarer aliases like objc @compatibility_alias,
in order to be have a concrete API that's easy to understand.
- implicitly desugared by the hasDeclaration ASTMatcher, to avoid
breaking existing patterns and following the precedent of ElaboratedType.
Scope:
- This does not cover types associated with template names introduced by
using declarations. A future patch should introduce a sugar TemplateName
variant for this. (CTAD deduced types fall under this)
- There are enough AST matchers to fix the in-tree clang-tidy tests and
probably any other matchers, though more may be useful later.
Caveats:
- This changes a fairly common pattern in the AST people may depend on matching.
Previously, typeLoc(loc(recordType())) matched whether a struct was
referred to by its original scope or introduced via using-decl.
Now, the using-decl case is not matched, and needs a separate matcher.
This is similar to the case of typedefs but nevertheless both adds
complexity and breaks existing code.

I noticed that, while go-to-def works on cases like:
namespace ns {
template<typename T> struct Foo {};
}
using ::ns::Fo^o;
it only works because of the FileIndex. We can get definition location
directly from AST too.

References to fields inside anon structs contain an implicit children
for the container, which has the same SourceLocation with the field.
This was resulting in SelectionTree always picking the anon-struct rather than
the field as the selection.
This patch prevents that by claiming the range for the field early.

- 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)
