Benchmark: Prototype chains

Script Preparation code:

const level1 = {a: 1};
const level2 = {b: 1};
const level3 = {c: 1};
const level4 = {d: 1};
const level5 = {e: 1};

level2.__proto__ = level1;
level3.__proto__ = level2;
level4.__proto__ = level3;
level5.__proto__ = level4;

Tests:

level 5
for (var i=0; i<10000; i++) { level5.a; }
level 4
for (var i=0; i<10000; i++) { level4.a; }
level 3
for (var i=0; i<10000; i++) { level3.a; }
level 2
for (var i=0; i<10000; i++) { level2.a; }
level 1
for (var i=0; i<10000; i++) { level1.a; }
