#2065 — 22.1.3.*: Change [[DefineOwnProperty]] to DefinePropertyOrThrow


[[DefineOwnProperty]]() should be changed to DefinePropertyOrThrow() in:
- 22.1.3.1 Array.prototype.concat(...), steps 9.d.v.4.b and 9.e.i
- 22.1.3.7 Array.prototype.filter(...), step 14.d.v.1
- 22.1.3.15 Array.prototype.map(...), step 13.d.v
- 22.1.3.25 Array.prototype.splice(...), step 17.d.iii

Silent failures in [[DefineOwnProperty]]() should not be ignored. Only affects array subclasses.


good catch...
