My ideal resolution would simply be that the VC runtime provides the `std::exception` class even when `-fno-exceptions` is used, since that's what all other platforms do.

Would D103947 <https://reviews.llvm.org/D103947> be a more acceptable solution? I don't know why VC runtime doesn't provide `std::exception` but even if we can convince Microsoft to change their approach, it's going to take years for that change to roll out so that strategy is not feasible for us since we would like to start using libc++ on Windows now.
