Fallback to `hiDecl` when `extractDecl` fails
Sometimes, the declaration being exported is a subdecl (for instance, a
record accessor getting exported at the top-level). For these cases,
Haddock has to find a way to produce some synthetic sensible top-level
declaration. This is done with `extractDecl`.
As is shown by #1067, this is sometimes impossible to do just at a
syntactic level (for instance when the subdecl is re-exported). In these
cases, the only sensible thing to do is to try to reify a declaration
based on a GHC `TyThing` via `hiDecl`.
