Summary:
LSP is using Line & column as symbol position, clangd needs to transfer file
offset to Line & column when sending results back to LSP client, which is a high
cost, especially for finding workspace symbol -- we have to read the file
content from disk (if it isn't loaded in memory).
Saving these information in the index will make the clangd life eaiser.

Summary:
Pretty straight-forward, just count all the variable declarations in the function's body, and if more than the configured threshold - do complain.
Note that this continues perverse practice of disabling the new option by default.
I'm not certain where is the balance point between not being too noisy, and actually enforcing the good practice.
If we really want to not disable this by default, but also to not cause too many new warnings, we could default to 50 or so.
But that is a lot of variables too...
I was able to find one coding style referencing variable count:
- https://www.kernel.org/doc/html/v4.15/process/coding-style.html#functions
> Another measure of the function is the number of local variables. They shouldn’t exceed 5-10, or you’re doing something wrong.

Summary:
It is possible that there will be two different instantiations of
the printer template for a given type and some tests could end up calling the
wrong (default) one. For example, it was seen in CodeCompleteTests.cpp when
printing CompletionItems that it would use the wrong printer because the default
is also instantiated in ClangdTests.cpp.
With this change, objects that were previously printed with a custom Printer now
get printed through the operator<< which is declared alongside the class.
This rule of the thumb should make it less error-prone.

LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in
HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the
default macro instead of a reinvented one.
See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev.
No intended behavior change.

Explicitly include and build lib/Testing/Support from LLVM sources when
doing a stand-alone build. This is necessary since clangd tests started
to depend on LLVMTestingSupport library which is neither installed
by LLVM, nor built by clang itself.
Since completely separate build of clang-tools-extra is not supported,
this relies on variables set by clang CMakeLists.

Summary:
Calculating the include path from absolute file path does not always
work for all build system, e.g. bazel uses symlink as the build working
directory. The absolute file path from editor and clang is diverged from
each other. We need to address it properly in build sysmtem integration.
This patch worksarounds the issue by providing a hook in URI which allows
clients to provide their customized include path.

This is triggering on a pattern that's both too broad (const
std::string& members can be used safely) and too narrow (std::string is
not the only class with this problem). It has a very low true positive
rate, just remove it until we find a better solution for dangling string
references.

Summary:
Currently if a fix is attached directly to a diagnostic, we repeat the
diagnostic message as the fix message. From eyeballing the top diagnostics,
it seems describing the textual replacement would be much clearer.
e.g.
error: use of undeclared identifier 'goo'; did you mean 'foo'?
action before: use of undeclared identifier 'goo'; did you mean 'foo'?
action after: change 'goo' to 'foo'

Summary:
A common mistake that I have found in our codebase is calling a function to get an integer or enum that represents the type such as:
```
int numBytes = numElements * sizeof(x.GetType());
```
So this extends the `sizeof` check to check for these cases. There is also a `WarnOnSizeOfCall` option so it can be disabled.

This macro is widely used in many well-known projects, ex. Chromium.
But it's not set for clang-tidy, so for ex. DCHECK in Chromium is not considered as [[no-return]], and a lot of false-positive warnings about nullptr dereferenced are emitted.
This patch fixes the issue by explicitly added macro definition.
