Benchmark: Merging two arrays test

Tests:

Array.prototype.push for of
const base = [1]; const added = [1, 2, 3]; const combined = base; for (const item of added) { combined.push(item) }
array.push spread
const base = [1]; const added = [1, 2, 3]; const combined = base.push(...added);
array.concat
const base = [1]; const added = [1, 2, 3]; const combined = base.concat(added);
spread operator
const base = [1]; const added = [1, 2, 3]; const combined = [...base, ...added];
