See CR for details. This saves the created mutex in a mutex_array during Mutex construction so that all Mutex, not just the ones in mutexLocker.cpp can be printed in the hs_err file. ThreadCritical is used to protect the mutex_array, and to avoid UB should be used when printing the owned locks, but since that is done during error handling, this seemed better not to lock during error handling. There's 0 probability that another thread will be creating a lock during this error handling anyway.
Tested with tier1-8.
