Attempt to fix the problems with missing instances once more. The current problem is that in the case where a ModDetails is being constructed from its interface (in compilation manager modes) we weren't getting any instances because the instances are gotten from the [InstInfo] returned from tcInstDecls1, which only contains *source* instance declarations. Fix: return a list of DFuns defined in the current module from tcInstDecls1, to be plugged into the ModDetails later. Also: revert the previous change to the isLocalThing predicate, because now we really want to know which dfuns come from the current module. The comment about the iface_dfuns containing only package and local instances is incorrect in batch-compile mode, because we also demand-load stuff from home package interfaces, so I deleted this comment and fixed up some of the other commentary.
