Leszek Swirski 661726dd39 [runtime] Move profiler ticks from SFI to feedback vector (reland)
Reland of https://chromium-review.googlesource.com/c/544888/.

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.
