7029509: nightly failures after static fields in Class
Reviewed-by:

There were a few failures in hotspot-gc after the static fields in
Classes change.  Two failures are because of missed places where the
address of static fields were computed.  The third is because only
real Java klasses have a mirror now so they should be skipped when
updating the class redefinition statistics.  Tested with nsk hprof,
heapdump and the nsk/jvmti/scenarios tests.
