Adjust TypeDefn(), which is used by reportTypeLoop(), to work for nodes with no Ntype set (which are all nodes in -G=3 mode). Normally, reportTypeLoop() would not be called, because the types2 typechecker would have already caught it. This is a possible way to report an unusual type loop involving type params, which is not being caught by the types2 type checker.
