Make data dependency around HDeoptimize correct.

We use HDeoptimize in a few places, but when it comes to data
dependency we either:
- don't have any (BCE, CHA), in which case we should make sure no
  code that the deoptimzation guards moves before the HDeoptimize
- have one on the receiver (inline cache), in which case we can
  update the dominated users with the HDeoptimize to get the data
  dependency correct.
