Evaluation of clall to function with duplicate inputs

[Jesper Mattsson]

When you have two functions:

function f1
  input Real x;
  output Real y;
end f1;

function f2
  extends f1;
  input Real x;
  output Real y;
algorithm
  ...
end f2;

Then while constant evaluating f2 in the instance tree, then the value of the argument is saved on the x declared in f1, but lookup of any access in the algorithm gives the one in f2, and is thus evaluated to unknown.

Fixed evaluation of functions with inputs and/or outputs duplicated through inheritance.
