Reid Kleckner d2ed9d6b7e 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: Change AlignedCharArrayUnion to an alias of std::aligned_union_t, NFC"

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

This reverts commit 4d8bf870a8.

This reverts commit d10f9863a5.

Duncan P. N. Exon Smith d10f9863a5 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.

This reverts commit 5d74c43511.
The gtest tests appear to be flaky, and are failing in various places.

Saleem Abdulrasool 5d74c43511 DirectoryWatcher: add an implementation for Windows
This implements the directory watcher on Windows.  It does the most
naive thing for simplicity.  ReadDirectoryChangesW is used to monitor
the changes.  However, in order to support interruption, we must use
overlapped IO, which allows us to use the blocking, synchronous
mechanism.  We create a thread to post the notification to the consumer
to allow the monitoring to continue.  The two threads communicate via a
locked queue.

Jan Korous b724f3d4b3 [clang] DirectoryWatcher for Windows stubs (to fix build break).
This is just a code skeleton for DirectoryWatcher-windows.cpp so the
build on Windows stops breaking.
