SA: wrong size computation when JVM was built without AOT

When the JVM was built without AOT we observed the following test failure (note that AOT is currently unsupported on some platforms like e.g. PPC64):

TestInstanceKlassSize was failing because of wrong size computation.
The problem is that the implementations in the following files don't fit together:

src/hotspot/share/oops/instanceKlass.cpp:
bool InstanceKlass::should_store_fingerprint(bool is_hidden_or_anonymous)
bool InstanceKlass::has_stored_fingerprint()
They always return false when built without AOT.

src/jdk.hotspot.agent/share/classes/sun/jvm/hotspot/oops/InstanceKlass.java:
public static boolean shouldStoreFingerprint()
public boolean hasStoredFingerprint()
They return true in some cases regardless of whether JVM was built without AOT or not.
