*	Revert "[coroutines] Add std::experimental::task<T> type"	Brian Gesiak	2019-03-26	1	-284/+0
\| \| \| \| \| \| \| \|	This revision is causing build and test failures, such as http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux/builds/648/steps/test.libcxx/logs/stdio, so I'll revert it. llvm-svn: 357023
*	[coroutines] Add std::experimental::task<T> type	Brian Gesiak	2019-03-26	1	-0/+284
	Summary: Adds the coroutine `std::experimental::task<T>` type described in proposal P1056R0. See https://wg21.link/P1056R0. This implementation allows customization of the allocator used to allocate the coroutine frame by passing std::allocator_arg as the first argument, followed by the allocator to use. This supports co_awaiting the same task multiple times. The second and subsequent times it returns a reference to the already-computed value. This diff also adds some implementations of other utilities that have potential for standardization as helpers within the test/... area: - `sync_wait(awaitable)` - See P1171R0 - `manual_reset_event` Move the definition of the __aligned_allocation_size helper function from <experimental/memory_resource> to <experimental/__memory> so it can be more widely used without pulling in memory_resource. Outstanding work: - Use C++14 keywords directly rather than macro versions eg. use `noexcept` instead of `_NOEXCEPT`). - Add support for overaligned coroutine frames. This may need wording in the Coroutines TS to support passing the extra `std::align_val_t`. - Eliminate use of `if constexpr` if we want it to compile under C++14.
