The current issue is that MemRegions that are not ElementRegions are
pretty-printed if possible using printPrettyAsExpr. With FieldRegions, this
only works if the SuperRegion is not an ElementRegion. So my strategy is to
obtain the SuperRegion in case of an ElementRegion or FieldRegion and only for
the MemRegions that do not have a SuperRegion (e.g. ParamVarRegion) I use the
prettyprintExpr function.
