8000973: SA on windows thread inspection is broken
Summary: After bug 7161732, On Windows SA could not find correct address of thread_id of OSThread since _thread_id moved to end of the class . The presupposition of the address is following thread handle no longer stands. Fix by adding thread_id field to OSThread and getting the address directly from OSThread.
