I don't know. I never had a particular design to set breakpoint on
every overloaded function. In case of constructors/templates/inlined
function you are very likely to have no idea of the address of the instance
you care about. Overloaded functions are basically separate functions that
happen to share a part of the name, so user is much more likely to know
which function he wants to debug.
