  Test calling an overriden method.
  
  Note:
    This verifies that LLDB is correctly building the method overrides table.
    If this table is not built correctly then calls to overridden methods in
    derived classes may generate references to non-existant vtable entries,
    as the compiler treats the overridden method as a totally new virtual
    method definition.
