Remove generic parameters from type inference classes.

Remove generic parameters from type inference classes.

Previously, these classes were generic because we anticapted re-using
them with analyzer AST objects in order to do analyzer type inference.
But we've decided on a new technique for doing analyzer type
inference: infer at the kernel level and then transfer the inference
data to analyzer using the TypeInferenceListener.

So the generic parameters are no longer needed.
