We can exploit the fact that defunctionalization symbols are never partially applied to local variables to generate fewer defunctionalization symbols for definitions where local variables are in scope. I've written up the details in a new part of `Note [Defunctionalization game plan] (Wrinkle 1: Partial kinds)` in `D.S.TH.Promote.Defun`. This has no effect on any user-visible behavior—it is just an optimization. Fixes #592.
