Terminate in the unit tests
Summary:
Many of our tests need to initialize certain subsystems/plugins of LLDB such as
`FileSystem` or `HostInfo` by calling their static `Initialize` functions before the
test starts and then calling `::Terminate` after the test is done (in reverse order).
This adds a lot of error-prone boilerplate code to our testing code.
This patch adds a RAII called SubsystemRAII that ensures that we always call
::Initialize and then call ::Terminate after the test is done (and that the Terminate
calls are always in the reverse order of the ::Initialize calls). It also gets rid of
all of the boilerplate that we had for these calls.
Per-fixture initialization is still not very nice with this approach as it would
require some kind of static unique_ptr that gets manually assigned/reseted
from the gtest SetUpTestCase/TearDownTestCase functions. Because of that
I changed all per-fixture setup to now do per-test setup which can be done
by just having the SubsystemRAII as a member of the test fixture. This change doesn't
influence our normal test runtime as LIT anyway runs each test case separately
(and the Initialize/Terminate calls are anyway not very expensive). It will however
make running all tests in a single executable slightly slower.

LLVM's wchar to UTF8 conversion routine expects an empty string to store the output.
GetHostName() on Windows is sometimes called with a non-empty string which triggers
an assert. The simple fix is to clear the output string before the conversion.

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.

This patch removes the comments grouping header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

This patch extends the FileSystem class with a bunch of functions that
are currently implemented as methods of the FileSpec class. These
methods will be removed in future commits and replaced by calls to the
file system.
The new functions are operated in terms of the virtual file system which
was recently moved from clang into LLVM so it could be reused in lldb.
Because the VFS is stateful, we turned the FileSystem class into a
singleton.

Host depended on clang because HostInfo had a function to get
the directory where clang was installed. We move this over to
the clang expression parser plugin where it's more at home.

Inside Xcode and in Xcode toolchains LLDB is always in lockstep
with the Swift compiler, so it can reuse its Clang resource
directory. This allows LLDB and the Swift compiler to share the
same Clang module cache.

Summary:
In D39387, I was quick to jump to conclusion that ArchSpec has no
external dependencies. It turns there still was one call to
HostInfo::GetArchitecture left -- for implementing the "systemArch32"
architecture and friends.
Since GetAugmentedArchSpec is the place we handle these "incomplete"
triples that don't specify os or vendor and "systemArch" looks very much
like an incomplete triple, I move its handling there.
After this ArchSpec *really* does not have external dependencies, and
I'll move it to the Utility module as a follow-up.

Summary:
ArchSpec::SetTriple was taking a Platform as an argument, and used it to
fill in missing pieces of the specified triple. I invert the dependency
by moving this code to other classes. For this purpose, I've created
three new functions.
- HostInfo::GetAugmentedArchSpec: fills in the triple using the host
platform (this used to be implemented by passing a null platform
pointer). By putting this code in the Host module, we can provide a
way to anyone who does not have a platform instance (lldb-server) an
easy way to get Host data.
- Platform::GetAugmentedArchSpec: if you have a platform instance, you
can call this to let it fill in the triple.
- static Platform::GetAugmentedArchSpec: implements the "if platform ==
0 then use_host() else use_platform()" part.
