a7e5504d83 [cleanup] Stop using the now-unused deopt_count from feedback vector. 
Unfortunately, we still have to keep the field because GC mole and Torque
do not support platform specific padding well
(see http://crbug.com/v8/9287).

1297c928d5 [turbofan] Use load_mode feedback for HasProperty access 
ReduceJSHasProperty was always passing STANDARD_LOAD instead of using the load mode from
the feedback verctor. This was causing deopt loops when checking for out-of-bounds
indices.
