Right now, I'm finding that even if I go to grandchild.cpp, put my cursor on void Grandchild::foo(), and then select "Find Reference to Symbol Under Cursor", it shows me every instance of EVERY foo() called anywhere in the program, including the declarations/definitions of Abstract::foo(), Base::foo() and Child::foo(), which I don't care about at the moment.

FWIW, there are at least 3 cases when it is certainly known at compile time which overload is called:

1) if object is referenced by value:
  
  Grandchild blah;
  blah.foo();

2) fully qualified method call:

  Grandchild *blah = getFoo();
  blah->Grandchild::foo(); // or Base::foo() etc.

3) when foo() is final in Grandchild:
  
  Grandchild *blah = getFoo();
  blah->foo();
