https://bugs.openjdk.java.net/browse/JDK-8055069

Problem:
"Errata HSW136. Software Using Intel® TSX May Result in Unpredictable 
System Behavior."

Changes:
Require to specify UnlockExperimentalVMOptions flag together with 
UseRTMLocking flag on un-patched systems where CPUID allows it but is 
unsupported otherwise. This would be for experiments and research and 
not for production applications as the name suggests.
Give a warning on un-patched system when RTM is used.
I have to adjust several jtreg RTM tests.

Note, by default UseRTMLocking is off.

I ran compiler jtreg tests on un-patched system and on machine without RTM.

Thanks,
Vladimir
