[patch] smart pointer support

[sami wagiaalla <swagiaal at redhat dot com>]

The '->' operator can be overloaded in C++ and when overloaded it 
forwards the function call or member reference to the return type. Example:

template < typename Type> class SmartPointer{
  Type* p;
 public:
  SmartPointer(Type *pointer){
    p = pointer;
  }

  Type* operator->(){
    return p;
  }
};


class MyType{
  public:
  void foo(){
    printf("I am foo\n");
  }
};

int main(){
  MyType mt;

  SmartPointer<MyType> sp(&mt);

  sp->foo();

  return 0;
}

Here sp->foo() really means (sp->)->foo()

This patch adds support for that in gdb

This patch adds a test to the test suite to test for the functionality 
above and was regression tested by running the test suite on Fedora 13 
on x8664 with gcc 444
