[issue5211] Fix complex type to avoid coercion in 2.7.

Just to keep this discussion as clear as possible Mark, it was your first
option that I suggest is needed.

When that is done (as it was for a subclass of float in 2.6.6) it is
possible for the author of the subclass to implement commutative binary
operations (like + and * that must behave the same regardless of argument
order). Otherwise (as far as I can see) this cannot be done.
