Using `assert.AssertionError()` without the `new` keyword results
in a non-intuitive error:
```js
> assert.AssertionError({})
TypeError: Cannot assign to read only property 'name' of function 'function ok(value, message) {
if (!value) fail(value, true, message, '==', assert.ok);
}'

```
The `assert.AssertionError()` can only be used correctly with `new`,
so this converts it into a proper ES6 class that will give an
appropriate error message.
This also associates the appropriate internal/errors code with all
`assert.AssertionError` instances and updates the appropriate test
cases.
