- Ensure that no new OSThreads are created once the VM is in shutdown mode
- Do not query thread_list_head_ without a lock (this leads to the race which causes two threads to delete the lock and TLS at the same time)

fields in a thread (i.e fields that are not Dart VM related)
- Split the Thread structure to be a pure Dart per thread structure and add
a pointer to os_thread which points to the OSThread structure
- Change Schedule/UnSchedule to set the Dart Thread structure as the TLS of
the thread when it is inside the Dart world and reset the TLS back to the
OSThread strcuture when is exits the Dart World.
- Moved the stack_base and few stack size related functions to OSThread from Isolate

In release mode, there seems to be nothing to prevent this.
In debug mode, the "Verify" call waits for the sweeper, but there is still a race between the task count update and the ExitIsolateAsHelper call, which could cause problems.
Fix both of these, and add more assertions and verbose error messages.
- make sweeper task cleanly exit isolate *before* notifying
- wait for sweeper before shutting down isolate
- verbose pthread failures
