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.)

 var arr = [1];

 Object.defineProperty(arr, 1, { value: undefined, configurable: false });

 // no particular reason for 9 -- just enough to trigger property-cache code,

 // maybe start JITting a little

 for (var y = 0; y < 9; y++)

   arr.length = 1;
