What makes it slow is the DOM operation in every round of the loop.
Try to increment the

to a variable, and after the loop has finished, do the dom operation
document.getElementById("polyline").value = variable.
Internet Explorer is slow doing even string increments. That is why
you can often see that pieces of a string are pushed to an array and
in the end the array is joined. In your case it might be.
In the loop:
ddArray.push(point.lat().toFixed(6)+","+point.lng().toFixed(6));
And after the loop:
document.getElementById("polyline").value = ddArray.join("|");
You can also replace
point.lat().toFixed(6)+","+point.lng().toFixed(6)
by
point.toUrlValue()
