+The ``[[clang::coro_await_suspend_destroy]]`` attribute may be applied to a C++
+coroutine awaiter type.  When this attribute is present, the awaiter must
+implement ``void await_suspend_destroy(Promise&)``.  If ``await_ready()``
+returns ``false`` at a suspension point, ``await_suspend_destroy`` will be
+called directly, bypassing the ``await_suspend(std::coroutine_handle<...>)``
