rdar://164245530 Currently, we deterministically ensure that segregated objects will not be allocated next to another object with the same tag. This property should be extended to cover bitfit object allocations as well. We will not be able to use the same approach as before (i.e. parity odd/even) due to that depending on the slab-ness of the allocator, a property that bitfit allocators do not have.
