[Bug c++/39205] New: Warning when object syntax is used to call a static member function

["pgrealis at yahoo-inc dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I can't think of a scenario where one would want to write x.f() over X::f()
when f() is static.  I'd like a warning for this so I can catch with -Werror.
