Revert of RedirectNonUINonIOBrowserThreads to TaskScheduler by default on trunk. (patchset #3 id:40001 of https://codereview.chromium.org/2690183002/ )
Reason for revert:
Breaks some DBUS code that requests for a message loop
Original issue's description:
> RedirectNonUINonIOBrowserThreads to TaskScheduler by default on trunk.
>
> The addition of AssertWaitAllowed in BrowserMainLoop::ShutdownThreadsAndCleanUp()
> is required because joining is a "wait" operation. It wasn't required
> before because PlatformThread::Join (platform_thread_posix.cc) actually still
> does AssertIOAllowed() instead of AssertWaitAllowed() for legacy reasons
> (and I/O is allowed in shutdown already). But this CL enables the redirection
> which uses a WaitableEvent to mimic thread join (ref. BrowserThreadImpl::StopRedirectionOfThreadID():
> waiting on the exact same set of tasks it did prior to redirection).
