this system allows dialects to register named interfaces, which are collections of function pointers. an op can then implement this interface, providing callbacks for the interface's virtual function pointers. C code can request a pointer to an op's implementation of a given interface and call virtual functions with no knowledge required about the op itself. this functonality will also be extended to types, attributes, and dialects themselves.
