It went away.  Instead we use preciseTime() before and after.

> MJS has been the historical keeper of sunspider.  i woudl be happy to approve this if I was convinced there was no behavior change other than using a more precise timer.  Also, doesn't v8-builds use this file as well?

V8 version 3.8.6 (candidate) [console: readline]
d8> run
(d8):1: ReferenceError: run is not defined

So we are already using JSC-specific API here; I don't see how v8 builds could be running this file.
