Conditional equations should also be allowed when depending from conditions on iterators

[Francesco Casella]

Please check ​Modelica.Electrical.QuasiStationary.Machines.Examples.TransformerTestbench. The NF fails with

[Modelica trunk/Electrical/QuasiStationary/MultiPhase.mo:672:11-672:68:writable]
Error: connect may not be used inside if-equations with non-parametric conditions
(found connect(deltaS.plugToPins_n.pin_n[j], deltaS.plugToPins_p.pin_p[j + 1])).

The offending code reads

      for j in 1:m loop
        if j < m then
          connect(plugToPins_n.pin_n[j], plugToPins_p.pin_p[j + 1]);
        else
          connect(plugToPins_n.pin_n[j], plugToPins_p.pin_p[1]);
        end if;
      end for;

I'm not sure if the specification covers this case explicitly, but obviously there is no reason to reject these equations, as the conditions are parametric once the loops are unrolled.

Fixed in b9d1619. The model now fails due to some Complex issues instead.
