This reverts commit a2fcdc7cc8.
Reason for revert: Large regressions in RCS (https://chromeperf.appspot.com/group_report?bug_id=740126)
Original change's description:
> [runtime] Move profiler ticks from SFI to feedback vector
>
> Instead of counting profiler ticks on the shared function info (which is
> shared between native contexts), count them on the feedback vector
> (which is not). This allows us to continue pushing optimization
> decisions off the SFI, onto the feedback vector.
>
> Note that a side-effect of this is that ICs don't have to walk the stack
> to reset profiler ticks, as they can access the feedback vector directly
> from their feedback nexus.
