[Martin Walsh]

Could I get a review for the following bug please:

JDK-8164002: Add a new CPU family (S_family) for SPARC S7 and above 
processors

https://bugs.openjdk.java.net/browse/JDK-8164002

Webrev is available here:

http://cr.openjdk.java.net/~mwalsh/JDK-8164004/


The changes add support for the SPARC-S processors, meaning the correct 
performance optimizations are made.


Thanks,

Martin
