Instead of calling the function constructor to compile script in Sky, we now concatenate strings. This has the advantage of making the line numbers generated in error messages correct but the disadvantage of being a hack. I've filed https://code.google.com/p/v8/issues/detail?id=3624 to request a proper API for this purpose. R=esprehn@chromium.org Review URL: https://codereview.chromium.org/688033003
