Oliver Gierke df9f8c417e DATACMNS-637 - Performance improvements.
Made ObjectInstantiator interface public as otherwise the generated class to implement it cannot access it and thus the usage of the ByteCodeGeneratingEntityInstantiator fails completely.

PreferredConstructor.isEnclosingClassParameter(…) now eagerly returns if the parameter itself is not an enclosing one and thus avoids a collection lookup and equals check. Moved equals check for the type to the very end of the equals check to increase the chances that other inequality guards kick in earlier.

AbstractMappingContext now leaves the non-null-check for getPersistentEntity(…) to the factory method of ClassTypeInformation.

We now pre-calculate the hash codes for TypeInformation implementations as far as possible as the instances are used as cache keys quite a lot. The same applies to AbstractPersistentProperty.

BasicPersistentEntity now uses an ArrayList we sort during the verify() phase to mimic the previous behavior wich was implemented using a TreeSet as ArrayLists are way more performant when iterating over all elements which doWithProperties(…) is doing which is used quite a lot.

BeanWrapper now avoids the getter lookup if field access is used.

SimpleTypeHolder now uses a CopyOnWriteArrySet to leniently add types detected to be simple to the set of simple types to avoid ongoing checks against the inheritance hierarchy.
