-// Generate the self-patching vtable method:

-// This method will be called (as any other Klass virtual method) with
-// the Klass itself as the first argument. Example:
-//
-//   oop obj;
-//   int size = obj->klass()->klass_part()->oop_size(this);
-//
-// for which the virtual method call is Klass::oop_size();.
-//
-// The dummy method is called with the Klass object as the first
-// operand, and an object as the second argument.
-//
-
-//=====================================================================
-
-// All of the dummy methods in the vtable are essentially identical,
-// differing only by an ordinal constant, and they bear no releationship
-// to the original method which the caller intended. Also, there needs
-// to be 'vtbl_list_size' instances of the vtable in order to
-// differentiate between the 'vtable_list_size' original Klass objects.
