This rename was suggested by gclayton as a way to silence gcc warnings; the warning is emitted when there is an overloaded function in a base class (Platform) for which a derived class redefines one of the overloads but not the other (because doing so hides the other overload from users of the derived class). By giving the two methods different names, the situation is avoided. llvm-svn: 199504
