* Extensible error class.
*
* The built-in Error class is not actually a constructor, but a factory. It
* doesn't operate on `this`, so if we call it as `super()` it doesn't do
* anything useful.
*
* Nonetheless it does create objects that are instanceof Error. In order to
* easily subclass error we need our own base class which mimics that behavior
* but with a true constructor.
*
* Note that this code is specific to V8 (due to `Error.captureStackTrace`).
