De-virtualized JSCell::toNumber
​https://bugs.webkit.org/show_bug.cgi?id=69858

Reviewed by Sam Weinig.

Source/JavaScriptCore:

Removed JSCallbackObject::toNumber because its no longer necessary since
JSObject::toNumber now suffices since we implicitly add valueOf to an object's
prototype whenever a convertToType callback is provided.

• API/JSCallbackObject.h:
• API/JSCallbackObjectFunctions.h:
• JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def:

De-virtualized JSCell::toNumber, JSObject::toNumber, and JSString::toNumber.

• runtime/JSCell.cpp:

(JSC::JSCell::toNumber):

• runtime/JSCell.h:
• runtime/JSObject.h:
• runtime/JSString.h:

Removed JSNotAnObject::toNumber because its result doesn't matter and it implements
defaultValue, therefore JSObject::toNumber can cover its case.

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

Source/JavaScriptGlue:

Removed UserObjectImp::toNumber because it's no longer necessary since
JSObject::toNumber can cover this case.

• UserObjectImp.cpp:
• UserObjectImp.h:
