We had code in NewPtr() to set the HasTParam/HasShape flag as needed for the cached ptr element if it wasn't set correctly based on its Elem. This was causing the race mentioned in the issue. But that setting code is no longer needed, as long as we call SetRParams() soon after calling NewIncompleteNamedType(), before creating/translating the underlying type (which we do). The HasTParam/HasShape attribute can only come from setting of rparams or a direct typeparam/shape somewhere in the underlying type, both of which don't depend on recursion, etc. (as long as the rparams are set early). Added a check that HasTParam/HasShape are set correctly for the cached pointer/slice elems in NewPtr() and NewSlice().
