Sam McCall 4d006520b8 [clangd] Clean up unused includes. NFCI
Add includes where needed to fix build.
Haven't systematically added used headers, so there is still accidental

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:

Jan Svoboda 622354a522 [llvm][ADT] Implement `BitVector::{pop_,}back`
LLVM Programmer’s Manual strongly discourages the use of `std::vector<bool>` and suggests `llvm::BitVector` as a possible replacement.

Currently, some users of `std::vector<bool>` cannot switch to `llvm::BitVector` because it doesn't implement the `pop_back()` and `back()` functions.

To enable easy transition of `std::vector<bool>` users, this patch implements `llvm::BitVector::pop_back()` and `llvm::BitVector::back()`.

David Goldman d75fb1ee79 [clangd] Support `#pragma mark` in the outline
Xcode uses `#pragma mark -` to draw a divider in the outline view
and `#pragma mark Note` to add `Note` in the outline view. For more
information, see https://nshipster.com/pragma/.

Since the LSP spec doesn't contain dividers for the symbol outline,
instead we treat `#pragma mark -` as a group with children - the
decls that come after it, implicitly terminating when the symbol's
parent ends.

The following code:

```
@implementation MyClass

- (id)init {}

- (int)foo;
@end
```

Would give an outline like

```
MyClass
        > Overrides
                    > init
        > Public Accessors
                    > foo

Sam McCall bca3e24139 [clangd] Move DraftStore from ClangdLSPServer into ClangdServer.
ClangdServer already gets notified of every change, so it makes sense for it to
be the source of truth.
This is a step towards having ClangdServer expose a FS that includes dirty
buffers: D94554

Related changes:
 - version is now optional for ClangdServer, to preserve our existing fuzziness
   in this area (missing version ==> autoincrement)
 - ClangdServer::format{File,Range} are now more regular ClangdServer functions
   that don't need the code passed in. While here, combine into one function.
 - incremental content update logic is moved from DraftStore to
   ClangdLSPServer, with most of the implementation in SourceCode.cpp.
   DraftStore is now fairly trivial, and will probably ultimately be
   *replaced* by the dirty FS stuff.

Kadir Cetinkaya 538c2753f3
[clangd] locateMacroAt handles patched macros
Summary: Depends on D79992.

This patch changes locateMacroAt to perform #line directive substitution
for macro identifier locations.

We first check whether a location is inside a file included through
built-in header. If so we check whether line directive maps it back to
the main file, and afterwards use TokenBuffers to find exact location of
the identifier on the line.

Instead of performing the mapping in locateMacroAt, we could also store
a mapping inside the ParsedAST whenever we use a patched preamble. But
that would imply adding more responsibility to ParsedAST and paying for
the mapping even when it is not going to be used.

====

Go-To-Definition:

Later on these locations are used for serving go-to-definition requests,
this enables jumping to definition inside the preamble section in
presence of patched macros.

=====

Go-To-Refs:

Macro references in main file are collected separetely and stored as a
map from macro's symbol id to reference ranges. Those ranges are
computed inside PPCallbacks, hence we don't have access to TokenBuffer.

In presence of preamble patch, any reference to a macro inside the
preamble section will unfortunately have the wrong range. They'll point
into the patch rather than the main file. Hence during findReferences,
we won't get any ranges reported for those.

Fixing those requires:
- Lexing the preamble section to figure out "real range" of a patched
  macro definition
- Postponing range/location calculations until a later step in which we
  have access to tokenbuffers.

This patch trades some accuracy in favor of code complexity. We don't do
any patching for references inside the preamble patch but get any
reference inside the main file for free.
