Swapnil Gaikwad 91e3243d60 Extend GetIterator bytecode to perform JSReceiver check on object[Symbol.iterator]() 
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.
