Call `os_log_fault` when an lldb assert fails. We piggyback off
`LLVM_SUPPORT_XCODE_SIGNPOSTS`, which also depends on `os_log`, to avoid
having to introduce another CMake check and corresponding define.
This patch also adds a small test using lldb-test that verifies we abort
with a "regular" assertion when asserts are enabled.

Our code for locating the shared library directory works via dladdr (or
the windows equivalent) to locate the path of an address known to reside
in liblldb. This works great for C++ programs, but there's a catch.
When (lib)lldb is used from python (like in our test suite), this dladdr
call will return a path to the _lldb.so (or such) file in the python
directory. To compensate for this, we have code which attempts to
resolve this symlink, to ensure we get the canonical location. However,
here's the second catch.
On windows, this file is not a symlink (but a copy), so this logic
fails. Since most of our other paths are derived from the liblldb
location, all of these paths will be wrong, when running the test suite.
One effect of this was the failure to find lldb-server in D96202.
To fix this issue, I add some windows-specific code to locate the
liblldb directory. Since it cannot rely on symlinks, it works by
manually walking the directory tree -- essentially doing the opposite of
what we do when computing the python directory.
To avoid python leaking back into the host code, I implement this with
the help of a callback which can be passed to HostInfo::Initialize in
order to assist with the directory location. The callback lives inside
the python plugin.
I also strenghten the existing path test to ensure the returned path is
the right one.

It seems like only the unittests are building with
BUILD_WITH_INSTALL_RPATH set to OFF. Of course when I did my last change
I only ran check-lldb-unit. Not sure why this difference exists, why
would you even install the unittest?
For the LLDB framework we do need different build and install RPATHs.
Currently that logic lives downstream. I plan to upstream that in the
near future. For now I'm just trying to make it possible to run the
test.
The install name for the Python 3 framework in Xcode is relative to
the framework's location and not the dylib itself.
@rpath/Python3.framework/Versions/3.x/Python3
This means that we need to compute the path to the Python3.framework
and use that as the RPATH instead of the usual dylib's directory.
This patch threads an lldb::DescriptionLevel through the typesystem to
allow dumping the full Clang AST (level=verbose) of any lldb::Type in
addition to the human-readable source description (default
level=full). This type dumping interface is currently not exposed
through the SBAPI.
The application is to let lldb-test dump the clang AST of search
results. I need this to test lazy type completion of clang types in
subsequent patches.

Seems like this code raised some alarm bells as it looks like an ArrayRef
to a temporary initializer list, but it's actually just calling the ArrayRef(T*, T*)
constructor. Let's clarify this and directly call the right ArrayRef constructor here.

This patch changes the way we initialize and terminate the plugins in
the system initializer. It uses an approach similar to LLVM's
TARGETS_TO_BUILD with a def file that enumerates the plugins.
Previous attempts to land this failed on the Windows bot because there's
a dependency between the different process plugins. Apparently
ProcessWindowsCommon needs to be initialized after all other process
plugins but before ProcessGDBRemote.

Generate the LLDB_PLUGIN_DECLARE macros with CMake and a def file. I'm
landing D73067 in pieces so I can bisect what exactly is breaking the
Windows bot.
Other plugins depend on DynamicLoaderDarwinKernel and which means we
cannot conditionally enable/build this plugin based on the target
platform. This means that it will be past of the list of plugins
initialized once that's autogenerated.
Summary:
All of our lookup APIs either use `CompilerDeclContext &` or `CompilerDeclContext *` semi-randomly it seems.
This leads to us constantly converting between those two types (and doing nullptr checks when going from
pointer to reference). It also leads to the confusing situation where we have two possible ways to express
that we don't have a CompilerDeclContex: either a nullptr or an invalid CompilerDeclContext (aka a default
constructed CompilerDeclContext).
This moves all APIs to use references and gets rid of all the nullptr checks and conversions.

LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch

This patch changes the way we initialize and terminate the plugins in
the system initializer. It uses an approach similar to LLVM's
TARGETS_TO_BUILD with a def file that enumerates the plugins.
The previously landed patch got reverted because it was lacking:
(1) A plugin definition for the Objective-C language runtime,
(2) The dependency between the Static and WASM dynamic loader,
(3) Explicit initialization of ScriptInterpreterNone for lldb-test.
All issues have been addressed in this patch.

After the recent change that grouped some of the ABI plugins together,
those plugins ended up with multiple initializers per plugin. This is
incompatible with my proposed approach of generating the initializers
dynamically, which is why I've grouped them together in a new entry

Apparently Linux and Windows have the exact opposite behavior when it
comes to inline declarations of external functions. On Linux they're
considered to be part of the lldb_private namespace, while on Windows
they're considered to be part of the top level namespace. Somehow on
macOS, it doesn't really matter and both are fine...
At this point I don't know what to do, so I'm just adding the
LLDB_PLUGIN_DECLARE macros again as originally proposed in D74245.
This is a step towards making the initialize and terminate calls be
generated by CMake, which in turn is towards making it possible to
disable plugins at configuration time.

Summary:
There's a fair amount of code duplication between the different ABI plugins for
the same architecture (e.g. ABIMacOSX_arm & ABISysV_arm). Deduplicating this
code is not very easy at the moment because there is no good place where to put
the common code.
Instead of creating more plugins, this patch reduces their number by grouping
similar plugins into a single folder/plugin. This makes it easy to extract
common code to a (e.g.) base class, which can then live in the same folder.
The grouping is done based on the underlying llvm target for that architecture,
because the plugins already require this for their operation.

Summary:
This change represents the move of ClangASTImporter, ClangASTMetadata,
ClangExternalASTSourceCallbacks, ClangUtil, CxxModuleHandler, and
TypeSystemClang from lldbSource to lldbPluginExpressionParserClang.h
This explicitly removes knowledge of clang internals from lldbSymbol,
moving towards a more generic core implementation of lldb.

Summary:
This commit renames ClangASTContext to TypeSystemClang to better reflect what this class is actually supposed to do
(implement the TypeSystem interface for Clang). It also gets rid of the very confusing situation that we have both a
`clang::ASTContext` and a `ClangASTContext` in clang (which sometimes causes Clang people to think I'm fiddling
with Clang's ASTContext when I'm actually just doing LLDB work).
I also have plans to potentially have multiple clang::ASTContext instances associated with one ClangASTContext so
the ASTContext naming will then become even more confusing to people.
