VMMaker 4.7.9

Make NewObjectMemory work with a standard Interpreter.

This update provides sufficient support for an Interpreter to run on a NewObjectMemory, rather than the normal Interpreter with ObjectMemory configuration. To reproduce this, make InterpreterPrimitives be a subclass of NewObjectMemory, and disable the error notifiers in CCodeGenerator>>addMethod: and CCodeGenerator>>checkClassForNameConflicts:.

The Interpreter/NewObjectMemory configuration is only lightly tested, and may be somewhat slower than the normal Interpreter/ObjectMemory configuration. The purpose of this update is to provide support for StackInterpreter (not yet working) which requires a NewObjectMemory.

NewObjectMemory>>clearLeakMakeAndMapAccessibleObjects is temporarily disabled, as it requires support in platforms/Cross/vm/sqHeapMap.c not yet present SVN trunk.

There are no changes to standard VM generation with VMMakerTool, which continues to generate a standard Interpreter with ObjectMemory, and there are no functional changes to the standard interpreter VM as a result of this update.
