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.)

 // vim: set ts=8 sts=4 et sw=4 tw=99:

 function f() {

     return [[], [], [], []];

 }

 function setelem(obj, key, val) {

     obj[key] = val;

 }

 // Generate IC

 setelem([], 0, "hi");

 setelem([], 0, "hi");

 var arrays = f();

 var evil = { };

 Object.defineProperty(evil, "1", { set: function (v) { this.ham = v; } });

 Array.prototype.__proto__ = evil;

 var k = arrays[0];

 setelem(k, 1, "yam");

 assertEq(k.ham, "yam");
