Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)

 // for-of can iterate over generator-iterators produced by generator-expressions.

 function g() {

     yield 1;

     yield 2;

 }

 var it = g();

 for (var i = 0; i < 10; i++) {

     let prev = it;

     it = (k + 1 for (k of prev));

 }

 var arr = [v for (v of it)];

 assertEq(arr.join(), "11,12");
