Write CGen as bidirectional. Some caveats.
 
This implementation works for non-implicits, but when you have implicit
paramters, polymorphism, and ANF, the bidirectional approach doesn't
quite work. You end up with something like

```haskell
let anf0 :: SST Int Int Int = (>>) @Int @Int @Int in get >> get
```

The problem is that the implicit information simply travels up, not
down! Seems the solution is to either not use bidi, or make fresh and <:
allocate implicit paramters and solve for them.
