[PATCH] D14653: [libcxx] Introduce the mechanism for fixing -fno-exceptions test failures.

Further refined the changes to `__config` header.

- Now there's only one `_LIBCPP_THROW` macro, which does the right thing depending on the availability of exceptions.
- Made `__libcxx_noexceptions_report` not take in the exception object as an argument. The only argument for this was that with the exception object, we can produce a better error message. But this has the downside that the caller will have to instantiate an exception object even in the no-exceptions mode. Since the `LIBCPP_THROW` macro now requires an explicit error message for the no-exception variant, there's really no need to fiddle with the exception object.
