gcc invokes cc1 through a path deduced from argv[0] therefore it must

This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/.
This is needed to avoid a circular dependency when using the bitstream
code for parsing optimization remarks.
Since Bitcode uses Core for the IR part:
libLLVMRemarks -> Bitcode -> Core
and Core uses libLLVMRemarks to generate remarks (see
IR/RemarkStreamer.cpp):
Core -> libLLVMRemarks
we need to separate the Bitstream and Bitcode part.
For clang-doc, it seems that it doesn't need the whole bitcode layer, so
I updated the CMake to only use the bitstream part.

Summary:
Previously, we only collect refs of the symbols which are declared in
the preamble and referenced in the main file, it works well when the
main file is .cpp file.
However, when the main file is .h file (when opening a .h file in the
editor), we don't collect refs of the symbol declared in this file, so we miss
these refs in our dynamic index.
A typical scenario:
1. Open Foo.h (which contains class Foo)
2. Open Foo.cpp, call find references for Foo
And we only get refs from Foo.cpp.

Summary:
- when we hit the cache, the reported filename should be that of the
cache query, not that of the cache store. This matches behaviors of
common FSes, and avoids triggering difficult edge cases in
FileManager when files are being moved around concurrently.
- filename comparisons (both cache queries and == mainfile checks)
should fold away . and .. in paths. These can appear when relative
paths occur in compile_commands.json. (gn does this).

The bitstream reader handles errors poorly. This has two effects:
* Bugs in file handling (especially modules) manifest as an "unexpected end of
file" crash
* Users of clang as a library end up aborting because the code unconditionally
calls `report_fatal_error`
The bitstream reader should be more resilient and return Expected / Error as
soon as an error is encountered, not way late like it does now. This patch
starts doing so and adopting the error handling where I think it makes sense.
There's plenty more to do: this patch propagates errors to be minimally useful,
and follow-ups will propagate them further and improve diagnostics.

Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

2. jump to Foo.h, call go-to-def on Foo in Foo.h
we can't go back to Foo.cpp -- because we open Foo.cpp, Foo.h in clangd, both
files have Foo symbol (one with def&decl, one with decl only), we randomely
choose one.

Summary:
The existing implementation (which triggers on }) is fairly simple and
has flaws:
- doesn't trigger frequently/regularly enough (particularly in editors that type the }
for you)
- often reformats too much code around the edit
- has jarring cases that I don't have clear ideas for fixing
This implementation is designed to trigger on newline, which feels to me more
intuitive than } or ;.
It does have allow for reformatting after other characters - it has a
basic behavior and a model for adding specialized behavior for
particular characters. But at least initially I'd stick to advertising
\n in the capabilities.
This also handles comment splitting: when you insert a line break inside
a line comment, it will make the new line into an aligned line comment.
Working on tests, but want people to patch it in and try it - it's hard to
see if "feel" is right purely by looking at a test.

Instantiate a ClangTidyDiagnosticConsumer also for the plugin case and
let it forward the diagnostics to the external diagnostic engine that is
already in place.
One minor difference to the clang-tidy executable case is that the
compiler checks/diagnostics are referred to with their original name.
For example, for -Wunused-variable the plugin will refer to the check as
"-Wunused-variable" while the clang-tidy executable will refer to that
as "clang-diagnostic- unused-variable". This is because the compiler

llvm-svn: 362279
Summary:
Clangd's framework is assembled by copying binaries from the lib and bin directories into a bundle shape. This results in an invalid bundle code signature because the signature only applies to the binaries not the resources.
This patch adds two new options to `llvm_codesign` to enable re-signing the library and XPC service as bundles.
The `BUNDLE_PATH` option allow specifying an explicit path to codesign, which enables signing bundles which aren't generated using CMake's `FRAMEWORK` or `BUNDLE` target properties.
The `FORCE` option allows re-signing binaries that have already been signed. This is required for how clangd exposes the clangd library and tools as both XPC and non-XPC services using the same binary.

without recording the tokens.
The added hook is very low-level and reconstructing the expanded token

replications of the same symbol reaches merging step.
