Original issue's description:
> Reland #1: "base: Implement GetCurrentThreadPriority."
>
> The Chrome thread priority is saved in the thread dictionary during
> SetCurrentThreadPriority(). This seemed a better approach than using
> thread_policy_get(), since there are 4 Chrome priorities which won't cleanly map
> to thread flavors.
