Summary:
Some implicit/built-in decls lack the source location
information. Fallback to OrigD that we've seen in the source code
instead of the canonical one in those cases.

Summary:
The bugprone-too-small-loop-variable check often catches loop variables which can represent "big enough" values, so we don't actually need to worry about that this variable will overflow in a loop when the code iterates through a container. For example a 32 bit signed integer type's maximum value is 2 147 483 647 and a container's size won't reach this maximum value in most of the cases.
So the idea of this option to allow the user to specify an upper limit (using magnitude bit of the integer type) to filter out those catches which are not interesting for the user, so he/she can focus on the more risky integer incompatibilities.
Next to the option I replaced the term "positive bits" to "magnitude bits" which seems a better naming both in the code and in the name of the new option.

Summary:
Part of re-landing rC356541 with D59599. Changes the way we store
template arguments, previous patch was storing them inside Name field of Symbol.
Which was violating the assumption:
```Symbol::Scope+Symbol::Name == clang::clangd::printQualifiedName```
which was made in multiple places inside codebase. This patch instead moves
those arguments into their own field. Currently the field is meant to be
human-readable, can be made structured if need be.

`Transport.h` does not include `Features.inc`. However, since it is used in a
subdirectory, it cannot directly include the header as it is not available.
Include `Features.inc` in `ClangdLSPServer.h` prior to the inclusion of
`Transport.h` which will provide the interfaces in `ClangdMain.cpp` where the
symbol `newXPCTransport` will not be defined due to it being preprocessed away
since the configuration is not passed along to the initial inclusion.

Summary:
There are cases where Sema can't tell that "foo" in foo::Bar is a
namespace qualifier, like in incomplete macro expansions.
After this patch, if sema reports no specifier but it looks like there's one in
the source code, then we take it into account.
Reworked structure and comments in getQueryScopes to try to fight
creeping complexity - unsure if I succeeded.
I made the test harder (the original version also passes).

At Mozilla we are using this tool in order to perform review-time static-analysis, since some patches contain a large number of files we've discovered this issue, where `stderr` gets mixed with `stdout` thus obfuscating our possibility to parse the output.
The patch that we are currently use can be found [here](https://searchfox.org/mozilla-central/source/build/build-clang/clang-tidy-8.patch).
This is just an upstream of the original patch.

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.)
