Current GetIterator bytecode loads and calls @@iterator property on a given object. This change extends the bytecode functionality to check whether the value returned after calling @@iterator property is a valid JSReceiver. The bytecode throws SymbolIteratorInvalid exception if the returned value is not a valid JSReceiver. This change absorbs the functionality of additional two bytecodes - JumpIfJSReceiver and CallRuntime, that are part of the iterator protocol in the GetIterator bytecode.
