Seems both make_typename_type and finish_decltype_type can return
error_mark_node even if the arguments passed to those aren't error_mark_node
(as they are called tf_none, no diagnostics is emitted).
The question is what strip_typedefs should do if that happens?  Shall it return
error_mark_node, or the original type, something different?  The end of the
function assumes that result is a valid type.
