avoid flattening ropes when creating substrings

Creating a substring caused the original string be flattened if it was in the rope form. This could use significant amount of memory by reducing buffer sharing between strings.

Add a rope specific substring function that constructs the substring by reusing the rope fibers instead of flattening the rope.

No change observed in SunSpider.
