David Goldman 88a2ac6ad6 [clangd] Improve XRefs support for ObjCMethodDecl
- Correct nameLocation to point to the first selector fragment instead
  of the - or +

- getDefinition now searches through the proper impl decls to find
  the definition of the ObjCMethodDecl if one exists

Christian Kühnel 2f8da95e07 [clangd][nfc] cleanup of remaining clang-tidy findings
There were some left-overs (or new things) from the previous patches.

This will get us down to 0 open findings except:
clang-tidy is complaining in some files about
`warning: #includes are not sorted properly [llvm-include-order]`
however, clang-format does revert these changes.
It looks like clang-tidy and clang-format disagree there.

Not sure how we can fix that...

Christian Kühnel 8edfc2f814 [clangd] Cleanup of readability-identifier-naming
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:

[clangd] Add ObjC method support to prepareCallHierarchy
This fixes "textDocument/prepareCallHierarchy" in clangd for ObjC methods. Details at https://github.com/clangd/vscode-clangd/issues/247.

clangd uses Decl::isFunctionOrFunctionTemplate to check if the decl given in a prepareCallHierarchy request is eligible for prepareCallHierarchy. We change to use isFunctionOrMethod which includes functions and ObjC methods.

Sam McCall 7d2fba8ddb [clangd] ObjC fixes for semantic highlighting and xref highlights
- 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)

Aleksandr Platonov 2e25be0b61 [clangd] Add main file macros into the main-file index.
This patch is a try to fix `WorkspaceSymbols.Macros` test after D93796.
If a macro definition is in the preamble section, then it appears to be in the preamble (static) index and not in the main-file (dynamic) index.
Thus, a such macro could not be found at a symbol search according to the logic that we skip symbols from the static index if the location of these symbols is inside the dynamic index files.
To fix this behavior this patch adds main file macros into the main-file (dynamic) index.
