Try to load accessClass without synchronization
In EsotericSoftware/kryo#422 it's reported that the sychronization in `ConstructorAccess.get` on the loader is causing significant thread contention. This change tries to prevent this, via double checked locking. Because it's the same pattern it's also done for `FieldAccess` and `MethodAccess` as well.
