See [here](https://docs.google.com/document/d/1rWcueFwIfZox6GKVGxiUG4cBzjrZ6djXiIDGyJDtrE4/edit?tab=t.0) for the design doc. This also removes the default value of the `result_type_inst_id` parameter of `HandleAction`, moves it before the action in the parameter list, and documents it. This solves two problems: - The default made it easy to forget, leading to unnecessary `TypeOfInst` instructions. - When it was present, putting it after the fairly "bulky" action argument tended to make the callsite harder to read.
