Summary:
- Removed the move-constructibe requirement from copy-assignable.
- Updated `__assign_alt` such that we direct initialize if
`_Tp` can be `nothrow`-constructible from `_Arg`, or `_Tp`'s
move construction can throw. Otherwise, construct a temporary and move it.
- Updated the tests to remove the pre-LWG2904 path.
Depends on D32671.

This reverts commit r304462, thereby re-enabling two tests under ubsan.
We expect these tests to pass now that PR33271 is fixed.

The shell test versions didn't get all of the flags normal tests
do, specifically warning flags. This patch makes them .pass.cpp tests,
and uses a lit.local.cfg to add -fcoroutines-ts and to make them
UNSUPPORTED when that flag isn't available.

from_address requires that the provided pointer refer to the suspended coroutine,
which doesn't have a type, or at least not one knowable by the user. Therefore
every use of `from_address` with a typed pointer is almost certainly a bug.
This behavior is a part of the TS specification, but hopefully it will be
in the future.

More tests to come. I think that from_address overload should be deleted
or ill-formed, except for the 'void*' one; The user cannot possibly
have a typed pointer to the coroutine state.

This patch adds end-to-end/breathing tests for coroutines
into libc++. The tests aren't specifically to test libc++ requirements
but instead are intented to ensure coroutines are working fine in general.
Although libc++ isn't exactly the most correct place for these tests
to live, there is one major advantage. The libc++ test suite is also
used by MSVC and by adding the tests here it ensures they will be
run against all currently available coroutine implementations.

The tests were previously guarded by #if defined(_LIBCPP_VER) || defined(_MSVC_STL_VER),
which is both incorrect (e.g. _LIBCPP_VERSION) and unneeded. Although the tests are
technically non-standard (yet) they are supported by both libc++ and MSVC's STL.
libstdc++ doesn't regularly use the test suite so I'm not concerned about guarding these
tests for them.

This patch updates the promise() member to match the current spec.
Specifically it removes the non-const overload and make the return
type of the const overload non-const.
This patch also makes the ASSERT_NOT_NOEXCEPT tests libc++ specific,
since other implementations may be free to strengthen the specification.

This C++17 Core Language feature isn't necessary when testing std::byte.
It's a minor convenience, but it limits test coverage to very new compilers.
This part activates the tests for more compilers.

This patch cleans up a number of issues reported by STL, including:
1) Fix duplicate is_convertible test.
2) Move non-standard reference_wrapper tests under test/libcxx
3) Fix assumption that sizeof(wchar_t) == 32 in the codecvt and
wstring_convert tests.

This patch removes the clear() member from <string_view>. The
modifier was removed from the TS before it ever landed in the standard.
There is no reason libc++ should be providing this method.

This patch attempts to make lookup_classname.pass.cpp usable against
other STL implementations by guarding the use of __regex_word. That being
said it seems likely that the test is still non-conforming due to how
libc++ handles the "w" character class.
