propEqual should treat TypedArray as arrays

Tell us about your runtime:

• QUnit version: current
• What environment are you running QUnit in? (e.g., browser, Node): browser/any
• How are you running QUnit? (e.g., script, testem, Grunt): QUnit

What are you trying to do?

I'm trying to use deepEqual to compare an array with a typedarray instance

Code that reproduces the problem:

var { test } = QUnit;

test('float64Array', t => {
  var sample = new Float64Array([1, 2, 3, 4, 5, 6, 7, 8])
  var src = new Float32Array(sample.buffer, 0, 2);

  src[0] = 42;

  sample.set(src, 1);

  t.deepEqual(sample, [1.0000002464512363, 42, 1.875, 4, 5, 6, 7, 8])
})

If you have any relevant configuration information, please include that here:

What did you expect to happen?

being able to compare values between instances

What actually happened?

Start with the reported deepEqual reproduction using Float64Array, Float32Array, and a regular array. Determine how propEqual/deepEqual currently compares typed arrays and define completion as correctly comparing the values between typed-array and array instances; the payload names no files or tests to run.
