8e2d4ad9c5 [libcxx] Make UNSUPPORTED for std::async test more fine grained
The test was previously marked as unsupported on all Apple platforms, when
we really just want to mark it as unsupported for previously shipped dylibs
on macosx.

385cc71138 [libcxx] Mark std::async race condition test as unsupported on Darwin
PR38682 added a test to check for a race condition in std::future.
Part of the fix is part of the dylib, but there is no released version
of mac OS X that ships a dylib containing the fix. Hence, this test can
(and sometimes does) when testing on OS X. This commit marks the test
as unsupported to avoid spurious failures.

39ad1d12c1 [libc++] Remove race condition in std::async
Summary:
The state associated to the future was set in one thread (with synchronization)
but read in another thread without synchronization, which led to a data race.

e3a71a295e [libcxx] Recover no-exceptions XFAILs - I
First batch of changes to get some of these XFAILs working in the
no-exceptions libc++ variant.

Changed some XFAILs to UNSUPPORTED where the test is all about exception
handling. In other cases, used the test macros TEST_THROW and
TEST_HAS_NO_EXCEPTIONS to conditionally exclude those parts of the test
that concerns exception handling behaviour.

1e5a4a4a71 Fix or move various non-standard tests.
This patch does the following:

* Remove <__config> includes from some container tests.
* Guards uses of std::launch::any in async tests because it's an extension.
* Move "test/std/extensions" to "test/libcxx/extensions"
* Moves various non-standard tests including those in "sequences/vector",
  "std/localization" and "utilities/meta".

cc2e93cff0 Make it possible to build a no-exceptions variant of libcxx.
Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.

This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

56a599b976 Fix PR23293 - Do not unlock shared state before notifying consumers.
Within the shared state methods do not unlock the lock guards manually. This
could cause a race condition where the shared state is destroyed before the
method is complete.
