Benchmark: small Array vs TypedArray read performance

Script Preparation code:

"use strict";
const arr = new Array(64);
for (let i=0; i<64; i++) { arr[i] = i };
const typedArr = new Uint8Array(64);
for (let i=0; i<64; i++) { typedArr[i] = i };

Tests:

Array read
"use strict"; let _; for (let i=0, len=arr.length; i<len; i++) { _ = arr[i] };
TypedArray read
"use strict"; let _; for (let i=0, len=typedArr.length; i<len; i++) { _ = typedArr[i] };
