1. Setting the IC data array. This may have caused corrupt IC data seen by the
background compiler when cloning IC data.
2. Reading the thread_interrupt_disabled_ flag. This was reported as a race with TSAN.

Also:
- Reaps exited threads in the thread pool before putting
a thread on the idle list so that a new arriving task
isn't blocked on a supposedly idle thread in the middle
of a join.
- Stops trying to join eventhandler threads on
Windows. Now that we're using the correct exit() call,
we probably don't have to worry about exit code pollution,
so joining the threads is unnecessary.

API changes:
- Remove isolate specific Timeline APIs.
- Remove Dart_EmbedderTimelineGetTimeline callback.
- Add Dart_TimelineEvent so that arbitrary trace events can be added.
Internal changes:
- Remove isolate specific streams which were never used or controllable from outside the VM.

- Don't disable thread creation until isolates have shutdown.
- A thread-pool thread may try to start up after thread creation has
been disabled. We must reap the Worker objects for these threads.
- A thread may try to start up after OSThread::thread_list_lock_ has
been destroyed. Detect this.

- 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)

Creates an OSThread in OSThread::Current() if a thread doesn't
already have one.
Also removes the setup of an unneeded StackZone from a Timeline API
function.

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
