Fix #11473.
I've added a check in the zonker for representation polymorphism.
I don't like having this be in the zonker, but I don't know where
else to put it. It can't go in TcValidity, because a clever enough
user could convince the solver to do bogus representation polymorphism
even though there's nothing obviously wrong in what they wrote.
Note that TcValidity doesn't run over *expressions*, which is where
this problem arises.
In any case, the check is simple and it works.
test case: dependent/should_fail/T11473
