RFR (S) : 8014362 : Need to expose some processor features via Unsafe interface

[Vladimir Kozlov]

Sorry, I am late to this discussion.

I think, sun.zip.clmulSupported approach is only temporary solution. As 
Christian told we would need more CPU information for Graal.
We should start discussing (new RFE) about new JVM - JAVA API to pass 
information about hybrid hw environment (GPU+CPU+etc) JVM is running on.

An other solution for current problem could be resurrection of 
sun.cpu.isalist property (bug 6340855).

Thanks,
Vladimir
