I want this PR to be clear message that we deprecate all RTM related flags with goal to remove all of them and RTM code from HotSpot. 
Actually `java.1` man page listed `RTMAbortRatio` even so it is experimental. It listed product flags as well.
Which reminds me that I need to update `java.1` man page to move these flags to `DEPRECATED JAVA OPTIONS` section.
