Original issue's description:
> Refactor script position calculation
>
> Script position calculation logic (i.e. line & column numbers for a
> given code position) is now based on a single method
> Script::GetPositionInfo(). Refactored related code in isolate.cc and
> js/messages.js to use the new method and removed the line_ends JS
> accessor.
