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.)

 function C() {

     this.m = function () {};  // JSOP_SETMETHOD

 }

 var a = [new C, new C, new C, new C, new C, new C, new C, new C, new C];

 var b = [new C, new C, new C, new C, new C, new C, a[8],  new C, new C];

 var thrown = 'none';

 try {

     for (var i = 0; i < 9; i++) {

 	a[i].m();

 	b[i].m = 0.7;  // MethodWriteBarrier required here

     }

 } catch (exc) {

     thrown = exc.name;

 }

 assertEq(thrown, 'TypeError');
