* Cover optional's emplace-from-initializer_list overload
* Verify that any::emplace and optional::emplace return a reference to the correct type even for throwing cases.

This patch XFAIL's a number of tests under test/libcxx when on Windows.
These failures need more investigation or patches to either Clang or libc++
but for now we don't want them to prevent the bot from going green.

Summary:
libc++abi is never the right option for LIBCXX_TARGETING_MSVC, since it
targets the Itanium ABI, whereas MSVC uses the Microsoft ABI. Make the
default ABI be vcruntime when targeting MSVC even if libc++abi is
present in the tree.

Previously the ATOMIC_<TYPE>_LOCK_FREE macros were implemented
using __GCC_ATOMIC_<TYPE>_LOCK_FREE but GCC specific macros
are defined when -fms-compatibility is specified.
To avoid this Libc++ now tries to use the newly added
__CLANG_ATOMIC_<TYPE>_LOCK_FREE macros instead, and only falls
back to the GCC versions when the Clang ones aren't available.

Previously both the static version of libc++ and the
import library for the DLL had the same name, 'c++.lib'.
This patch renames the static library on Windows to be `libc++.lib`
so it no longer conflicts. This naming convention is consistent with
other windows libraries.

I'm currently trying to get a libc++ Windows builder working on appveyor.
This patch adds the configuration file needed to build libc++ on Appveyor.
Details of where the buildbot can be found will come later

_LIBCPP_ABI_MICROSOFT is more appropriate to use here, since the
conditionals are controlling Microsoft mangling. It wasn't used
originally since it didn't exist at the time.

These tests were unconditionally asserting that optional and unique_ptr declare throwing hashes, but MSVC++ implements conditional noexcept forwarding that of the underlying hash function. As a result we were failing these tests but there's nothing forbidding strengthening noexcept in that way.
Changed the ASSERT_NOT_NOEXCEPT asserts to use types which themselves have non-noexcept hash functions.
