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 R=johnmccutchan@google.com, zra@google.com Review URL: https://codereview.chromium.org/1439483003 .
