Wrong flattening of element-wise operators

[sjoelund.se]

Wrong flattening of element-wise operators. Consider:

function f
  input Real r1[:];
  input Real r2[size(r1,1)];
  output Real o[size(r1,1)];
algorithm
  o := r1 .* r2;
end f;

model M
  Real r[:] = f({1,2,3},{4,5,6});
end M;

omc prints:

function f
  input Real[:] r1;
  input Real[size(r1, 1)] r2;
  output Real[size(r1, 1)] o;
algorithm
  o := r1 * r2;
end f;

Which is wrong since r1 * r2 returns a scalar Real. This is an annoyance when debugging.

Fixed in r15776. We don't actually save the exact operator that the user used, so we don't know whether they were written as element-wise or not (in many cases it doesn't matter). Element-wise operators are now output when they are the only option, while 'normal' operators are output for the cases where it doesn't matter.
