RFR: 8294759: Print actual lock/monitor ranking

[Aleksey Shipilev]

When relative lock ranks are changing, it is useful to see what are the final lock ranks are. It can be dumped as optional logging shortly after VM startup. 

Sample output:


$ build/linux-x86_64-server-fastdebug/images/jdk/bin/java -Xlog:vmmutex
