Summary: Implements https://github.com/google/sanitizers/issues/835. Flush stdout before exiting in test cases. Since the atexit hook is used for exit reports, pending prints to stdout can be lost if they aren't flushed before calling exit(). Expect tests to have non-zero exit code if exit() is called.
