Fixed. It was indeed a good bug to catch - probably led to real link

* Fix a recomp bug: make classes/datatypes depend directly on DFuns
(#4469)
And remove the old mechanism of recording dfun uses separately,
because it didn't work.
This wiki page describes recompilation avoidance and fingerprinting.
I'll update it to describe the new method and what went wrong with the
old method:
