I don't know what you mean. You're not restoring any old state, you're moving
state into the new CGM. The whole thing is an imperative operation, it's just
being done in a destructor for no particular reason.
```
std::unique_ptr<CodeGenModule> newBuilder(new CodeGenModule(...));
Builder->moveLazyEmissionStateInto(newBuilder.get());
Builder = newBuilder;
```
