Revert "ADT: Migrate users of AlignedCharArrayUnion to std::aligned_union_t, NFC"

We determined that the MSVC implementation of std::aligned* isn't suited
to our needs. It doesn't support 16 byte alignment or higher, and it
doesn't really guarantee 8 byte alignment. See
https://github.com/microsoft/STL/issues/1533

Also reverts "ADT: Remove AlignedCharArrayUnion, NFC" to bring back
AlignedCharArrayUnion.

ADT: Migrate users of AlignedCharArrayUnion to std::aligned_union_t, NFC

Prepare to delete `AlignedCharArrayUnion` by migrating its users over to
`std::aligned_union_t`.

I will delete `AlignedCharArrayUnion` and its tests in a follow-up
commit so that it's easier to revert in isolation in case some
downstream wants to keep using it.

[Clang] Migrate llvm::make_unique to std::make_unique

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.

[clang][DirectoryWatcher][NFC] Swapping asserts for llvm fatal_error in create

I also have replaced all the instances of
"auto DW = DirectoryWatcher::create" with
llvm::Expected<std::unique_ptr<DirectoryWatcher>> DW = DirectoryWatcher::create
to make it more clear that DirectoryWatcher::create is returning an Expected.

I've also allowed for logAllUnhandledErrors to consume errors in the case were
DirectoryWatcher::create produces them.

[clang][DirectoryWatcher] Adding llvm::Expected error handling to create.

Prior to this patch Unix style errno error reporting from the inotify layer was
used by DirectoryWatcher::create to simply return a nullptr on error. This
would generally be ok, except that in LLVM we have much more robust error
reporting through the facilities of llvm::Expected.

The other critical thing I stumbled across was that the unit tests for
DirectoryWatcher were not failing abruptly when inotify_init() was reporting an
error, but would continue with the testing and eventually hit a deadlock in a
pathological machine state (ie in the unit test, the return nullptr on ::create
was ignored).

Generally this pathological state never happens on any build bot, so it is
totally understandable that it was overlooked, but on a Linux desktop running
a dubious desktop environment (which I will not name) there is a chance that
said desktop environment could use up enough inotify instances to exceed the
user's limit. These are the conditions that led me to hit the deadlock I am
addressing in this patch with more robust error handling.

With the new llvm::Expected error handling when your system runs out of inotify
instances for your user, the unit test will be forced to handle the error or
crash and report the issue to the user instead of weirdly deadlocking on a
condition variable wait.

[NFC] avoid AlignedCharArray in clang

As discussed in D65249, don't use AlignedCharArray or std::aligned_storage. Just use alignas(X) char Buf[Size];. This will allow me to remove AlignedCharArray entirely, and works on the current minimum version of Visual Studio.
