JDK-8047290 - Make Mutex::_no_safepoint_check_flag locks verify that this lock never checks for safepoint
Description
8047290 changed mutexLocker.cpp's def macro to have _mutex_array[_num_mutex] instead of _mutex_array[_num_mutex++], which means the array and _num_mutex aren't initialized properly. 

This breaks print_owned_locks_on_error and would manifest as a lie when provoking a vmError when global VM locks are held.
Comments
Closed as a dup of the bug that Coleen filed yesterday.
