 Restore unwind information generation

 While we want to reduce the amount of information generated into
 debug_info, it really doesn't make sense to remove block information
 for unwinding.

 This is a simple oversight introduced in 4ab57024, which severly
 reduces the usefulness of generated unwind data. Thanks to bitonic
 for spotting this!
