Comment (by bgamari):

 I think we all agree that the simplifier is not at fault here. Indeed the
 approach that duog mentions comment:25 is roughly what osa1 and I have
 discussed. However, it's slightly tricky as unfoldings are currently
 dropped before we make it to `core2Stg` (in CorePrep). I doubt this will
 unacceptably increase the number of emitted cost centers although I've
 been wrong before.
