------- Additional Comments from Andreas Kling <andreas.kling at nokia.com>
Updated to address Darin's comments.

* Replaced constructor bool parameter with enum ArrayCreationMode {
CreateCompactUninitialized, CreateInitialized }
* Added JSArray::uncheckedSetIndex(unsigned i, JSValue v)

I don't understand how we should initialize this array without looping though.
