Original commit message:
[CloneObjectIC] clone MutableHeapNumbers only if !FLAG_unbox_double_fields
Change the macros added in bf84766a2cd3e09070adcd6228a3a487c8dc4bbd to
only do the hard work if FLAG_unbox_double_fields is unset (otherwise,
they will attempt to dereference raw float64s, which is bad!)
Also adds a write barrier in CopyPropertyArrayValues for each store if
it's possible that a MutableHeapNumber is cloned.
