I thought it'd be better to minimise the difference between the tests. Adding the instructions into the old-format test doesn't hurt it IMO. In a future patch I will possibly be adding some `NewDebugInfoFormat`-specific behaviour, but I think minimising the difference is still worthwhile. What do you think?
