Summary:
Before this PR, `modernize-use-using` would transform the typedef in
```
template <typename a> class TemplateKeyword {
typedef typename a::template f<> e;
typedef typename a::template f<>::d e2;
};
```
into
```
template <typename a> class TemplateKeyword {
using d = typename a::b<>;
using d2 = typename a::template a::b<>::c;
};
```
The first one is missing the `template` keyword,
the second one has an extra `a::` scope. Both result
in compilation errors.

Summary:
This patch allows using installed gRPC to build two simple tools which
currently provide the functionality of looking up the symbol by name.
remote-index-client is a simplified version of dexp which connects to
remote-index-server passes lookup requests.
I also significantly reduced the scope of this patch to prevent large changelist
and more bugs. The next steps would be:
* Extending Protocol for deep copies of Symbol and inherit RemoteIndex from
Index to unify the interfaces
* Make remote-index-server more generic and merge the remote index client with
dexp
* Modify Clangd to allow using remote index instead of the local one for all
global index requests

Summary:
Previously, the check would fix
```
using fn = void(int);
void f(fn *);
void test() {
// CHECK-MESSAGES: :[[@LINE+2]]:12: warning: parameter 'I' is unused
// CHECK-FIXES: {{^}} f([](int /*I*/) {
f([](int I) { return; });
}
```
into
`f([]() { return; });` which breaks compilation. Now the check is disabled from Lambdas.
The AST is not so easy to use. For
```
auto l = [](int) { return; };
f(l);
```
one gets
```
`-CallExpr <line:7:5, col:8> 'void'
|-ImplicitCastExpr <col:5> 'void (*)(fn *)' <FunctionToPointerDecay>
| `-DeclRefExpr <col:5> 'void (fn *)' lvalue Function 0x55a91a545e28 'f' 'void (fn *)'
`-ImplicitCastExpr <col:7> 'void (*)(int)' <UserDefinedConversion>
`-CXXMemberCallExpr <col:7> 'void (*)(int)'
`-MemberExpr <col:7> '<bound member function type>' .operator void (*)(int) 0x55a91a546850
`-ImplicitCastExpr <col:7> 'const (lambda at line:6:14)' lvalue <NoOp>
`-DeclRefExpr <col:7> '(lambda at line:6:14)':'(lambda at line:6:14)' lvalue Var 0x55a91a5461c0 'l' '(lambda at line:6:14)':'(lambda at line:6:14)'
```
There is no direct use of the `operator()(int I)` of the lambda, so the `!Indexer->getOtherRefs(Function).empty()`
does not fire. In the future, we might be able to use the conversion operator `operator void (*)(int)` to mark
the call operator as having an "other ref".

- Update 1
builds a preamble, and an AST. Caches the AST.
- Update 2
Invalidates the cache, preamble hasn't changed.
- Update 3
Invalidates the cache, preamble hasn't changed
- Read
builds AST using preamble v1, and caches it.
preamble for v2 gets build, cache isn't invalidated since preamble is same.
generateDiags tries to reuse cached AST but latest version is 3 not 2, so
assertion fails.

This returns incremental highlights as a set of edits against the

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 triggers on types and function calls with namespace qualifiers. The
action is to remove the qualifier and instead add a "using" statement at
appropriate place.
It is not always clear where to add the "using" line. Right now we find
the nearest "using" line and add it there, thus keeping with local
convention. If there are no usings, we put it at the deepest relevant
namespace level.
This is an initial version only. There are several improvements that
can be made:
* Support for qualifiers that are not purely namespace (e.g. record
types, etc).
* Removing qualifier from other instances of the same type/call.
* Smarter placement of the "using" line.

It is used by code completion and signature help. Code completion
already uses a special no-compile mode for missing preambles, so this change is
a no-op for that.
As for signature help, it already blocks for a preamble and missing it implies
clang has failed to parse the preamble and retrying it in signature help likely
will fail again. And even if it doesn't, request latency will be too high to be
useful as parsing preambles is expensive.

Take this example yaml.

Length: 0
ReplacementText: ' {'
- FilePath: '/home/nathan/test/test.cpp'

...```
The current behaviour is to deduplicate the text insertions at Offset 28 and only apply one of the replacements.
However as both of these replacements came from the same translation unit we can be confident they were both meant to be applied together
The new behaviour won't deduplicate the text insertion and instead insert both of the replacements.
If the duplicate replacement is found inside different translation units (from a header file change perhaps) then they will still be deduplicated as before.

Summary:
Conservatively escaping everything is bad in coc.nvim which shows the markdown
to the user, and we have reports of it causing problems for other parsers.

Summary:
Previously, the range for "->" CXXOperatorCallExpr is the range of the
class object (not including the operator!), e.g. "[[vector_ptr]]->size()".
This patch includes the range of the operator, which fixes the issue
where clangd doesn't go to the overloaded operator "->" definition.

Summary:
Cover a new use case when using a 'signed char' as an integer
might lead to issue with non-ASCII characters. Comparing
a 'signed char' with an 'unsigned char' using equality / unequality
operator produces an unexpected result for non-ASCII characters.

Summary:
This facilitates performing go-to-definition in contexts where AST-based
resolution does not work, such as comments, string literals, preprocessor
disabled regions, and macro definitions, based on textual lookup in the index.

Summary: This adds a new module to enforce standards specific to the llvm-libc project. This change also adds the first check which restricts user from including system libc headers accidentally which can lead to subtle bugs that would be a challenge to detect.

Most clients of SourceManager.h need to do things like turning source
locations into file & line number pairs, but this doesn't require
bringing in FileManager.h and LLVM's FS headers.
The main code change here is to sink SM::createFileID into the cpp file.
I reason that this is not performance critical because it doesn't happen
on the diagnostic path, it happens along the paths of macro expansion
(could be hot) and new includes (less hot).
Saves some includes:
309 - /usr/local/google/home/rnk/llvm-project/clang/include/clang/Basic/FileManager.h
272 - /usr/local/google/home/rnk/llvm-project/clang/include/clang/Basic/FileSystemOptions.h
271 - /usr/local/google/home/rnk/llvm-project/llvm/include/llvm/Support/VirtualFileSystem.h
267 - /usr/local/google/home/rnk/llvm-project/llvm/include/llvm/Support/FileSystem.h
266 - /usr/local/google/home/rnk/llvm-project/llvm/include/llvm/Support/Chrono.h

Summary: Didn't realize that headers such as stddef.h may not exist on all systems. This patch mocks the headers so that the check's tests work on all systems. (:

Summary:
These functions only use the FormatStyle to obtain a LangOptions via
format::getFormattingLangOpts(), and some callers can more easily obtain
a LangOptions more directly.

Summary:
Created a general check for restrict-system-includes under portability as recommend in the comments under D75332. I also fleshed out the user facing documentation to show examples for common use-cases such as allow-list, block-list, and wild carding.
Removed fuchsia's check as per phosek sugguestion.

Summary:
The previous issue is that the item was filtered out by vscode, because
the prefix (which contains ".") are not matched against the filterText.
This patch works around it by adjusting the item filterText, inspired by
https://reviews.llvm.org/D75623.
