[Lois Foltan]

Please review this change to the template interpreter to support dynamic 
constant on Sparc.

open webrev at http://cr.openjdk.java.net/~lfoltan/bug_jdk8189916.0/webrev/
bug link https://bugs.openjdk.java.net/browse/JDK-8189916

All current jtreg dynamic constant tests pass when run on Sparc and have 
had (os.arch != "sparcv9") removed from their test description.

Testing: Sparc specific testing (hs-tier1-5, jdk-tier1-3) complete.
                All tier 1 platforms (hs-tier1-2) in progress.

Thanks,
Lois
