Summary:
When calling TUScehduler::runWithPreamble (e.g. in code compleiton), allow
entering a fallback mode when compile command or preamble is not ready, instead of
waiting. This allows clangd to perform naive code completion e.g. using identifiers
in the current file or symbols in the index.
This patch simply returns empty result for code completion in fallback mode. Identifier-based
plus more advanced index-based completion will be added in followup patches.

Requires making the llvm::MemoryBuffer* stored by SourceManager const,
which in turn requires making the accessors for that return const
llvm::MemoryBuffer*s and updating all call sites.
The original motivation for this was to use it and fix the TODO in
CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag
version of createFileID, and since llvm::SourceMgr* hands out a const
llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO
this way actually works, but this seems like a good change on its own
anyways.
No intended behavior change.

The CMake variable controlling if XPC code is built is called
CLANGD_BUILD_XPC but three places unintentionally checked the
non-existent variable CLANGD_BUILD_XPC_SUPPORT instead, which (due to
being nonexistent, and due to cmake) always silently evaluated to false.
Luckily the test still seems to pass, despite never running after being
added almost 3 months ago in r351280.

This is a bit of a larger change since this is the first (and as far as
I can tell only) place where the LLVM build produces macOS framework
bundles.
GN has some built-in support for this, so use that.
`gn help create_bundle` has a terse description (but it's a bit
outdated: `deps` must be `public_deps` and the conditionals in the
example in the help aren't quite right on non-iOS).
We need a new 'copy_bundle_data' tool, and since we copy the clangd.xpc
bundle as bundle_data into ClangdXPC.framework it needs to be able to
handle directories in addition to files.
GN also insists we have a compile_xcassets tool even though it's not
used. I just made that run `false`.
Despite GN's support for bundles, we still need to manually create the
expected symlink structure in the .framework bundle. Since this code
never runs on Windows, it's safe to create the symlinks before the
symlink targets exist, so we can just make the bundle depend on the
steps that create the symlinks. For this to work, change the symlink
script to create the symlink's containing directory if it doesn't yet
exist.
I locally verified that CMake and GN build create the same bundle
structure. (I noticed that both builds set LC_ID_DYLIB to the pre-copy
libClangdXPCLib.dylib name, but that seems to not cause any issues and
it happens in the CMake build too.)
(Also add an error message to clangd-xpc-test-client for when loading
the dylib fails – this was useful while locally debugging this.)

Summary:
Instead of tooling::Replacement. To avoid the need to have contents of

The Yaml module is missing on some systems and on many of clang buildbots.
But the test for run-clang-tidy.py doesn't fail due to 'NOT' statement masking a python runtime error.
This patch conditionally imports and enables the yaml module only if it's present in the system.
If not, then '-export-fixes' is disabled.

FileManager constructs a VFS in its constructor if it isn't passed one,
and there's no way to reset it. Make that contract clear by returning a

Remove CompilerInstance::VirtualFileSystem and
CompilerInstance::setVirtualFileSystem, instead relying on the VFS in
the FileManager. CompilerInstance and its clients already went to some
trouble to make these match. Now they are guaranteed to match.
As part of this, I added a VFS parameter (defaults to nullptr) to
CompilerInstance::createFileManager, to avoid repeating construction
logic in clients that just wanted to customize the VFS.

Summary:
clangd should be able to handle those with a proper compilation
database. However, users using 'nvcc' might start seeing spurious errors

My plan is to land and release this, but be ready to revert in
case of negative user feedback.

Analyzes OpenMP Structured Blocks and checks that no exception escapes
out of the Structured Block it was thrown in.
As per the OpenMP specification, structured block is an executable statement,
possibly compound, with a single entry at the top and a single exit at the
bottom. Which means, ``throw`` may not be used to to 'exit' out of the
structured block. If an exception is not caught in the same structured block
it was thrown in, the behaviour is undefined / implementation defined,
the program will likely terminate.
