Can this move to main, so that the message loop creation is localized?

#if defined(USE_OZONE)
base::MessageLoopForUI main_loop;
ui::OzonePlatform::InitializeForUI();
ui::OzonePlatform::InitializeForGPU();
#else
base::MessageLoopForIO message_loop;
#endif


That way too, we can remove RunHelper, and Bind(&base::TestSuite::Run,
base::Unretained(&test_suite)) directly.

Done. Much better in fact!
