Remove unneeded import
This fails in stage 2 when bootstrapping HEAD with HEAD due to -Werror. Turns out that tcInstBinders is now dead, and I'll remove it if nobody protests. I'd like to hear opinions whether tcInstBindersX then should be renamed to tcInstBinders.

In types, however, we're not so lucky, because *we cannot re-generalize*!
There is no lambda. So, we must be careful only to instantiate at the last
possible moment, when we're sure we're never going to want the lost polymorphism

To implement this behavior, we use bidirectional type checking, where we
explicitly think about whether we know the kind of the type we're checking
