[issue42147] Micro optimization for longrange iteration if step is 1

[Inada Naoki]

I agree that 1<<1000 is artificial example. But isn't this patch affects more regular patterns like [[] for _ in range(10000)]?

If we reject this, shouldn't we revert GH-22479 too?
I believe iterating range object is much more common use  case than range.index.
