At some point in the future these three symbols will become
C++11 atomic variables:
extern std::atomic<std::terminate_handler> __cxa_terminate_handler;
extern std::atomic<std::unexpected_handler> __cxa_unexpected_handler;
extern std::atomic<std::new_handler> __cxa_new_handler;
This change will not impact their ABI. But it will allow for a
portable performance optimization.
