Comment (by bgamari):

 In fact, it looks like the NCG already has read-only access to the
 `DebugBlock`s. Perhaps this idea isn't so crazy. The tricky part is
 ensuring that the debug entries remain properly sorted. Perhaps you could
 say something like "insert this `UnwindTable` after label `c2TN`"?
