Replace all `new stdClass()` with identical `(object)[]`

This should be the exact same. Its more a style change than anything.
So why do it then?
* I believe this is much less confusing than code mentioning a weird
"standard class". Barely anybody knows what this is, and what the
difference between "object" and "stdClass" is.
* The code is shorter.
* It's even faster. In my micro benchmark it's twice as fast.
