This reverts commit 91e3243d60.
Reason for revert: This deopts to the wrong point.
Original change's description:
> 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.
