Ouch, we are optimizing away {kCheckFloat64Hole} for some reason.

The following revision refers to this bug:
  https://chromium.googlesource.com/v8/v8.git/+/b8df95499338c86cf29bb8502a488a5ebf41c415

commit b8df95499338c86cf29bb8502a488a5ebf41c415
Author: bmeurer <bmeurer@chromium.org>
Date: Tue Jan 31 08:30:55 2017

[turbofan] Don't eliminate unused CheckFloat64Hole.

We cannot eliminate unused CheckFloat64Hole nodes, since loading from a
holey array can have side-effects, i.e. triggering getters in the
prototype chain.
