After the last fix in PprAbs.ppr_amode, we now need a cast from
StgClosure* to P_ in UPD_FRAME_UPDATEE. I'm not sure if this is the
nicest way to fix this, CgCon.cgReturnDataCon is another candidate. It
looks a little bit like PrimRep distinguishes not enough between the
different kind of pointers (there's no alternative for L_).
