Andreas Kling f47a14b9d6 LibJS: Use a premade shape when creating iterator result objects 
Instead of going through the steps of creating an empty new object,
and adding two properties ("value" and "done") to it, we can pre-bake
a shape object and cache the property offsets.

This makes creating iterator result objects in the runtime much faster.

47% speedup on this microbenchmark:

    function go(a) {
        for (const p of a) {
        }
    }
    const a = [];
    a.length = 1_000_000;
    go(a);
