Implement the Thread.sleep native method.
This makes returning TS_SLEEPING from JDWP simple and cheap, and
makes the stack dumps for sleeping threads more easily understood
by app developers (because there's no Object.wait magic going, and
the thread state is "Sleeping" rather than "TimedWaiting").
Also make Object.wait() a native method in its own right, so every call into
Monitor::Wait can explicitly pass the most appropriate ThreadState: kSleeping,
kWaiting, or kTimedWaiting.
Also add Thread.sleep and Object.wait(long, int) calls to the ThreadStress test.
