[PATCH] D20913: [asan] add primitives that allow coroutine implementations

I found one of these tests you are talking about in tsan/signal_sync.cc. It seems to trigger a signal every 10 microseconds, but even with that, isn't the probability that the signal triggers right in between __sanitizer_enter() and swapcontext() very low? I think it would be useful to add such a test, but not replace the current one by it, as the current one is deterministic and tests all tricky cases (except the signals).
