JDK-8172231 - SPARC ISA/CPU feature detection is broken/insufficient (on Solaris).
Description
The current ISA/CPU feature detection on the SPARC architecture is more or less absent on Linux (OL), providing only (very) limited support. There is no support for features provided by the newer Core C3 and C4 implementations.

Here, we should assume at least Oracle Linux 6.7 (JDK9). (?)
Comments
As a first step, introduce support for Core C3 and C4 features (i.e. on par with JDK-8172231).
