Addressing review comments:

- Renamed `throw_helper` as `__throw_helper` in order to not pollute the global namespace (@jroelofs)
- Made `try_buf` a `thread_local` in order to be able to support those tests the launch multiple threads.
- Introduced `__libcxx_noexceptions_abort()` as an intermediary between the no-exceptions library and the c library's `abort()` (@scott-0).
  - This had the side-benefit that we now don't have to hack around `assert()` in `noexcept.h` test support header; neat!
