JDK-8043913 - remove legacy code in SPARC's VM_Version::platform_features

JDK-8172231 - SPARC ISA/CPU feature detection is broken/insufficient (on Solaris).
Description
Currently, VM_Version::platform_features contains many definitions like

#ifndef AV_SPARC_ASI_BLK_INIT
#define AV_SPARC_ASI_BLK_INIT 0x0080  /* ASI_BLK_INIT_xxx ASI */
#endif

The reason for these definitions is that some versions of Solaris 10 do not define these constants.

In future versions of the JDK (possibly versions > 9) support for Solaris 10 will be dropped. When Solaris 10 is not supported anymore, we can get rid of these defines.
Comments
Fixed as part of JDK-8172231.
