Benchmark: Measuring impact of closures

Script Preparation code:

let [a,b] = Math.random() < 0.5 ? [5,9] : [9,5];

let sum = 0;

function hello(x) { sum += x };

function f1(x) { hello(x + a) };
function f2(x) { f2.hello(x + b) }; Object.defineProperty(f2, "hello", { value: hello });

function f3(x) { hello(x + b) };
function f4(x) { f4.hello(x + a) }; Object.defineProperty(f4, "hello", { value: hello });

function f5(x) { f5.hello(x + f5.n) }; Object.defineProperty(f5, "hello", { value: hello }); Object.defineProperty(f5, "n", { value: a });
function f6(x) { f6.hello(x + f6.n) }; Object.defineProperty(f6, "hello", { value: hello }); Object.defineProperty(f6, "n", { value: b });
