tyConRolesRepresentational is just a version of tyConRolesX, but specialised for a Representational argument. Saves a bit of extra argument passing and pattern matching, and tyConRolesX was often called when we knew the argument role was Representational. Rather to my surprise this made the compiler allocate 5% less for tests T9872{b,c,d}. At least I think it's this commit. Good thing, regardless.
