Review request for JDK-8141446: Cache Class.forName for permanently loaded classes

[Attila Szegedi]

Please review JDK-8141446 "Cache Class.forName for permanently loaded classes" at <http://cr.openjdk.java.net/~attila/8141446/webrev.jdk9> for <https://bugs.openjdk.java.net/browse/JDK-8141446>

This was obtained by profiling the cost of compile-octane.js test, and has an overall benefit on “ant test”. On my machine “ant test” went from 12m30s to 10m30s.

Thanks,
  Attila.
