Stack overflow when importing function into same scope

[Per Östlund]

The following model causes a stack overflow:

package P
  import P2 = P;

  function f
    output Real r = 2.0;
  end f;

  constant Real c = P2.f();
end P;

The reason for this is that when instantiating the constant c it tries to look up the function P2.f. The lookup then tries to instantiate the package P when it looks for f, which causes it to instantiate c, etc.

Works with scodeFlatten

Fixed since SCodeFlatten is now on by default. Test case added in revision 8881.
