This reverts https://codereview.chromium.org/2077613002/. The check was supposed to tell us whether GPU process main thread's message pump was signaled at the time of the hang. In practice 100% of crash dumps had the negative result. After some additional research I realized that that was a false negative and that this check doesn't work as expected with auto-reset events. I confirmed that an auto-reset event gets promptly reset back to non-signaled when it gets signaled as long as there is at least one thread already waiting on it. That is the case even when when the target thread is never scheduled to run. The check would work with a manual-reset event but apparently it is useless in the case of an auto-reset event.
