Background-indexing is fine, because it uses GlobalCompilationDatabase
to fetch the compile commands (hence uses CommandMangler), and creates
invocation through buildCompilerInvocation.
Depends on D106639.

We can build it with -Werror=global-constructors now. This helps
in situation where libSupport is embedded as a shared library,
potential with dlopen/dlclose scenario, and when command-line
parsing or other facilities may not be involved. Avoiding the
implicit construction of these cl::opt can avoid double-registration
issues and other kind of behavior.

For files directly under clangd/, -Iclang-tools-extra/clangd (and the
equivalent for generated files) are not required, as CMake/the compiler puts
these directories on the include path by default.
However this means each subdirectory needs to
include_directories(.. ${CMAKE_CURRENT_BINARY_DIR}/..) etc, and this
proved annoying and error-prone to maintain and debug.
Since include_directories is inherited by subdirectories, we just
configure this explicitly at the top level instead.
This is a try to improve clangd-indexer tool performance:
- avoid processing already processed files.
- use different mutexes for different entities (e.g. do not block insertion of references while symbols are inserted)
Results for LLVM project indexing:
- before: ~30 minutes
- after: ~10 minutes

This reverts commit 3f76260dc0.
Breaks at least these tests on Windows:
Clang :: Driver/clang-offload-bundler.c
Clang :: Driver/clang-offload-wrapper.c
Use clang_target_link_libraries() in order to support linking against
libclang-cpp instead of static libraries.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Previously reverted in 364141 due to buildbot breakage, and fixed here
by making GeneralCategory global a ManagedStatic.
Summary:
This change processes `OptionCategory`s and `SubCommand`s as they
are seen instead of caching them in the Option class and processing
them later. Doing so simplifies the work needed to be done by the Global
parser and significantly reduces the size of the Option class to a mere 64
bytes.
Removing the `OptionCategory` cache saved 24 bytes, and removing
the `SubCommand` cache saved an additional 48 bytes, for a total of a
72 byte reduction.

Summary:
For counting number of references clangd was relying on merging every
duplication of a symbol. Unfortunately this does not apply to FileIndex(and one
of its users' BackgroundIndex), since we get rid of duplication by simply
dropping symbols coming from non-canonical locations. So only one or two(coming
from canonical declaration header and defined source file, if exists)
replications of the same symbol reaches merging step.
This patch changes reference counting logic to rather count number of different
RefSlabs a given SymbolID exists.

Summary:
Currently, we only do deduplication when we flush final results. We may
have huge duplications (refs from headers) during the indexing period (running
clangd-indexer on Chromium).
With this change, clangd-indexer can index the whole chromium projects
(48 threads, 40 GB peak memory usage).

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The new guideline is to qualify with 'llvm::' explicitly both in
'.h' and '.cpp' files. This simplifies moving the code between
header and source files and is easier to keep consistent.

This is the second part for introducing include hierarchy into index

Standardize on the most common namespace setup in our *.cpp files:
using namespace llvm;
namespace clang {
namespace clangd {
void foo(StringRef) { ... }
And remove redundant llvm:: qualifiers. (Except for cases like
make_unique where this causes problems with std:: and ADL).
This choice is pretty arbitrary, but some broad consistency is nice.
This is going to conflict with everything. Sorry :-/
Squash the other configurations:
A)
using namespace llvm;
using namespace clang;
using namespace clangd;
void clangd::foo(StringRef);
This is in some of the older files. (It prevents accidentally defining a
new function instead of one in the header file, for what that's worth).
B)
namespace clang {
namespace clangd {
void foo(llvm::StringRef) { ... }
This is fine, but in practice the using directive often gets added over time.
C)
namespace clang {
namespace clangd {
using namespace llvm; // inside the namespace
This was pretty common, but is a bit misleading: name lookup preferrs
clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using
directive is).

Interface is in one file, implementation in two as they have little in common.
A couple of ad-hoc YAML functions left exposed:
- symbol -> YAML I expect to keep for tools like dexp
- YAML -> symbol is used for the MR-style indexer, I think we can eliminate
this (merge-on-the-fly, else use a different serialization)

Given that the indexer binary is put directly into ./bin directory
