Message:

Unzip initialization lists and constructors in JSCell hierarchy (5/7)
​https://bugs.webkit.org/show_bug.cgi?id=67420

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

Completed the fifth level of the refactoring to add finishCreation()
methods to all classes within the JSCell hierarchy with non-trivial
constructor bodies.

This primarily consists of pushing the calls to finishCreation() down
into the constructors of the subclasses of the second level of the hierarchy
as well as pulling the finishCreation() calls out into the class's corresponding
create() method if it has one. Doing both simultaneously allows us to
maintain the invariant that the finishCreation() method chain is called exactly
once during the creation of an object, since calling it any other number of
times (0, 2, or more) will cause an assertion failure.
