• roll out ​https://bugs.webkit.org/show_bug.cgi?id=21732 to remove the JSValuePtr class, to fix two problems

1) slowness under MSVC, since it doesn't handle a

class with a single pointer in it as efficiently
as a pointer

2) uninitialized pointers in Vector

• JavaScriptCore.exp: Updated.

• API/APICast.h: (toRef):

• VM/Register.h: (JSC::Register::Register): Removed overload for JSCell and call to payload function.

• kjs/JSCell.h: Changed JSCell to derive from JSValue again. Removed JSValuePtr constructor. (JSC::asCell): Changed cast from reinterpret_cast to static_cast.

• kjs/JSImmediate.h: Removed JSValuePtr class. Added typedef back.

• kjs/JSValue.h: (JSC::JSValue::JSValue): Added empty protected inline constructor back. (JSC::JSValue::~JSValue): Same for destructor. Removed == and != operator for JSValuePtr.
