This adds a `forErrorHandling` to the `Throw` node. This is used that the `throw` is *not* present in the source code but added to ensure correctness and/or soundness of the generated code. This is used for instance in the lowering for handling duplicate writes to a late final field or for pattern assignments that don't match.
