[Bug c++/36796] New: Support c++ override keyword

["slime at apple dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I've seen references on the web to an "override" keyword that allows the
compiler to check method signatures are the same where intended, ie. instead of
creating a new virtual function when a subclasses override method no longer
matches the superclass. (Microsoft compilers.)  This would be a very good api
enhancement.

eg.:

struct I1 {
   virtual void f();
};

struct X : public I1 {
   virtual void f() override {}
};
