Add static ClassInfo structs to classes that override JSCell::getCallData

https://bugs.webkit.org/show_bug.cgi?id=69311

Reviewed by Darin Adler.

Source/JavaScriptCore: 

Added ClassInfo structs to each class that defined its own getCallData 
function but did not already have its own ClassInfo struct.  This is a 
necessary addition for when we switch over to looking up getCallData from 
the MethodTable in ClassInfo rather than doing the virtual call (which we 
are removing).  These new ClassInfo structs are public because we often 
use these structs in other areas of the code to uniquely identify JSC classes and 
to enforce runtime invariants based on those class identities using ASSERTs.
Also added new createStructure methods to those classes that didn't have 
them so that the new ClassInfo structs would be used when creating the Structures 
in these classes.
