Add static version of JSCell::visitChildren
​https://bugs.webkit.org/show_bug.cgi?id=68404

Reviewed by Darin Adler.

.:

In this patch we just extract the bodies of the virtual visitChildren methods
throughout the JSCell inheritance hierarchy out into static methods, which are
now called from the virtual methods. This is an intermediate step in trying to
move the virtual-ness of visitChildren into our own custom vtable stored in
ClassInfo. We need to convert the methods to static methods in order to be
able to more easily store and refer to them in our custom vtable since normal
member methods store some implicit information in their types, making it
impossible to store them generically in ClassInfo.
