Benchmark: Array vs TypedArray vs f32 write performance

Tests:

Array write
var array = new Array(100000).fill(0); for (let i=0; i<array.length; i++) { array[i] = array[i] + 1; }
TypedArray write
var typedArray = new Uint8Array(100000).fill(0); for (let i=0; i<typedArray.length; i++) { typedArray[i] = typedArray[i] + 1; }
f32
var typedArray = new Float32Array(100000).fill(0); for (let i=0; i<typedArray.length; i++) { typedArray[i] = typedArray[i] + 1; }
i32
var typedArray = new Uint32Array(100000).fill(0); for (let i=0; i<typedArray.length; i++) { typedArray[i] = typedArray[i] + 1; }
