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 consults Object.prototype when it encounters a hole.

 Object.prototype[1] = 'peek';

 var log = [];

 for (var x of [0, , 2, 3])

     log.push(x);

 assertEq(log[1], 'peek');

 assertEq(log.join(), "0,peek,2,3");
