Back out 97036ab72558 which inappropriately compared turds to third parties.

 // Array.prototype.pop does a strict assignment to this.length even if the

 // caller is nonstrict. Bug 886087.

 load(libdir + "asserts.js");

 // obj.length is read-only

 var obj = {pop: [].pop, 0: "zero"};

 Object.defineProperty(obj, "length", {configurable: true, value: 1, writable: false});

 assertThrowsInstanceOf(() => obj.pop(), TypeError);

 // obj.length has only a getter

 obj = {pop: [].pop, 0: "zero", get length() { return 1; }};

 assertThrowsInstanceOf(() => obj.pop(), TypeError);
