Added method to OverloadData to return the list of overloads without repetition.

The method OverloadData::overloadsWithoutRepetition() returns the
overload list of the OverloadData object removing "almost" duplicated
functions. For our purposes "foo()" and "foo()const" means the same,
so the constant version is removed.
