commit 8bd173472a9d6f46bd465633318d24ac4d4534de
Author: Bill Orr <billorr@chromium.org>

Fix some thread cleanup issues that can cause crashes or DCHECKs.

OpenVR and Oculus devices may be destroyed before the render loop is
created.  If this happens we may crash because we call render_loop_->IsRunning().

Next, if we don't call render_loop_->Stop(), the render_loop_'s bindings will be
destroyed on the main thread rather than the render loop thread.

BUG= 868072
