Previously, attempting to load a value from an invalid reference would cause a crash. We now return a CodeGenerationError rather than hitting an assertion. This is not a complete solution, as ideally we would want to return a ReferenceError, but this now matches the behavior we see when we attempt to store something to an invalid reference.
