Note that I "fixed" one case in PyPy: if the class C has no __iter__() but only __radd__(), and we call "somelist += C()".  This was done simply by having somelist.__iadd__(x) return NotImplemented in case x is not iterable, instead of propagating the TypeError.

This fix doesn't change the outcome in the case reported here: if there are two possible ways to get a valid answer, then PyPy will systematically prefer the way implemented by the LHS method over the way implemented by the RHS method, whereas CPython might not.
