Refactor JSC to replace JSCell::operator new with static create method
​https://bugs.webkit.org/show_bug.cgi?id=64466

Reviewed by Oliver Hunt (​[email protected]) and Darin Adler (Darin Adler).

First step in a longer refactoring process to remove the use of
operator new overloading in order to allocate GC objects and to replace
this method with static create methods for each individual type of heap-allocated
JS object. This particular patch only deals with replacing uses of
operator new within JSC proper. Future patches will remove it from the
parts that interface with the DOM. Due to the DOM's continued dependence
on it, operator new has not actually been removed from JSCell.
