Addressing review comments by @EricWF:

- Introduced `_LIBCPP_THROW` macro to appropriately throw or call the no-exceptions report routine to handle the exceptional situation (avoid the overhead of a function call in the default library). The compiler may be able to inline the call to `__throw_helper` to achieve the same effect, but wouldn't hurt to make it explicit.

- Renamed `__throw_helper` to `__libcxx_noexceptions_report` as appropriate.

- Added `_LIBCPP_NORETURN` qualifiers to both `__libcxx_noexceptions_report` and `__libcxx_noexceptions_abort`.
