BackendDAE cannot represent NORETCALL equations

BackendDAE cannot represent NORETCALL equations, which means I have no easy way to make the following code run :( We seem to store assert, terminate, etc on the side of the assertion. That might be possible here as well, I don't know these things...

model M
  Integer i;
equation
  when sample(0,0.1) then
    Modelica.Utilities.Streams.print("printing at time: " + String(time));
    i = pre(i) + 1;
  end when;
end M;

added support for it in r13351 with example testsuite/mosfiles/WhenNoRetCall

Example does not work because

undefined reference to `Modelica_Utilities_Streams_print'

[jfrenkel]

• works in r13361, maybe EQ_NORETCALL needs information about buildin function

[sjoelund.se]

Like this:

record STMT_NORETCALL
  Exp exp;
  ElementSource source "the origin of the component/equation/algorithm";
end STMT_NORETCALL;

Then you can inline it, too :p
