+ JSCallee unnecessarily overrides a bunch of things in the method table.
+ <https://webkit.org/b/142855>
+
+ Reviewed by Geoffrey Garen.
+
+ Remove JSCallee method table overrides that simply call to base class.
+ This makes JSFunction property slot lookups slightly more efficient since
+ they can take the fast path when passing over JSCallee in the base class chain.
