8258746: illegal access to global field _jvmci_old_thread_counters by terminated thread causes crash

[dean-long]

This change moves the access to the global field _jvmci_old_thread_counters from the thread destructor to JavaThread::exit(). See the JBS issue for more details. The free of _jvmci_counters is left in the destructor intentionally, as it is allocated in the JavaThread constructor and not all termination paths go through JavaThread::exit().
