Instead of redundantly storing both the return_type_id and return_storage_id, where the declared return type is just the type of the return storage, store only the return_storage_id.
Add a convenience property to get the declared return type of the function.
In addition to avoiding storing redundant information, this is a preparatory step for an upcoming change for generics support that will make it more expensive and awkward to store TypeIds in places other than the type of an instruction.
