7041244: JSR 292: Server VM gets a SEGV running a JCK test
Reviewed-by:

The call to check_klass_subtype in _adapter_check_cast uses O0 as a
temporary register which may be later used in the exception throwing
path in vmarg to reload the bad object.

The fix is to use O3 instead of O0 which is also free at this point.
