De-virtualize JSCell::toObject

Reviewed by Darin Adler.

• JavaScriptCore.exp:
• JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def:

De-virtualized JSCell::toObject and changed its implementation to manually check the
cases for JSString and JSObject rather than leaving it up to the virtual method call.

• runtime/JSCell.cpp:

(JSC::JSCell::toObject):

• runtime/JSCell.h:

Removed JSNotAnObject::toObject because the case for JSObject works for it.
Also removed JSObject::toObject because it was essentially the identity function,
which is not necessary since toObject is no longer virtual.

• runtime/JSNotAnObject.cpp:
• runtime/JSNotAnObject.h:
• runtime/JSObject.cpp:
• runtime/JSObject.h:

De-virtualized JSObject::toObject and JSString::toObject.

• runtime/JSString.h:
