d92b1ae1d7 Remove stat cache chaining as it's no longer needed after PTH support has been
removed

Stat cache chaining was implemented for a StatListener in the PTH writer so that
it could write out the stat information to PTH. r348266 removed support for PTH,
and it doesn't seem like there are other uses of stat cache chaining. We can
remove the chaining support.

0da49a7ef1 PR40096: Forwards-compatible with C++20 rule regarding aggregates not having user-declared ctors
Looks like these were in place to make these types move-only. That's
generally not a feature that the type should prescribe (unless it's an
inherent limitation) - instead leaving it up to the users of a type.

5313327f61 Add explicit dependency on clangSerialization for a bunch of components to fix -DBUILD_SHARED_LIBS=on build
This is a more thorough fix of rC348911.
The story about -DBUILD_SHARED_LIBS=on build after rC348907 (Move PCHContainerOperations from Frontend to Serialization) is:

1. libclangSerialization.so defines PCHContainerReader dtor, ...
2. clangFrontend and clangTooling define classes inheriting from PCHContainerReader, thus their DSOs have undefined references on PCHContainerReader dtor
3. Components depending on either clangFrontend or clangTooling cannot be linked unless they have explicit dependency on clangSerialization due to the default linker option -z defs. The explicit dependency could be avoided if libclang{Frontend,Tooling}.so had these undefined references.

This patch adds the explicit dependency on clangSerialization to make them build.

b2ac7eec42 clang::tooling::Diagnostic: Don't store offset in the scratch space.
These offsets are useless (and even harmful in certain cases) in exported
diagnostics. The test will be added to clang-tidy, since it's the main user of
the clang::tooling::Diagnostic class.

d8ebe7951d Make clang-based tools find libc++ on MacOS
Summary:
When they read compiler args from compile_commands.json.
This change allows to run clang-based tools, like clang-tidy or clangd,
built from head using the compile_commands.json file produced for XCode
toolchains.

On MacOS clang can find the C++ standard library relative to the
compiler installation dir.

The logic to do this was based on resource dir as an approximation of
where the compiler is installed. This broke the tools that read
'compile_commands.json' and don't ship with the compiler, as they
typically change resource dir.

To workaround this, we now use compiler install dir detected by the driver
to better mimic the behavior of the original compiler when replaying the
compilations using other tools.

This patch moves the virtual file system form clang to llvm so it can be

Concretely the patch:
 - Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
 - Moves the corresponding unit test from clang to llvm.
 - Moves the vfs namespace from clang::vfs to llvm::vfs.
 - Formats the lines affected by this change, mostly this is the result of
   the added llvm namespace.

e05bf60631 [Tooling] Improve handling of CL-style options
This patch fixes the handling of clang-cl options in InterpolatingCompilationDatabase.
They were previously ignored completely, which led to a lot of bugs:

Additional options were being added with the wrong syntax. E.g. a file was
specified as C++ by adding -x c++, which causes an error in CL mode.

The args were parsed and then rendered, which means that the aliasing information
was lost. E.g. /W4 was rendered to -Wall, which in CL mode means -Weverything.

CL options were ignored when checking things like -std=, so a lot of logic was
being bypassed.

2dbbd910dd [Tooling] Do not restore working dir in ClangTool
Summary:
Resolve all relative paths before running the tool instead.

This fixes the usage of ClangTool in AllTUsExecutor. The executor will
try running multiple ClangTool instances in parallel with compile
commands that usually have the same working directory.

Changing working directory is a global operation, so we end up
changing working directory in the middle of running other actions,
which leads to spurious compile errors.
