        Description

        While doing a change in related area, I noticed there is no IRIW handling block in accessor_entry when reading volatile fields. This probably breaks PPC64 Zero.

        There is a block in bytecodeInterpreter.cpp for common code:

                  if (cache->is_volatile()) {
                    if (support_IRIW_for_not_multiple_copy_atomic_cpu) {
                      OrderAccess::fence();
                    }

        AFAIU, this mostly affects 8u that does not have PPC64 port yet.
