Revert "Allow 64-bit offsets for raw_ptr arithmetic on 32-bit platforms"

This reverts commit c6b9b6d69063366a8593b0c96434d5ab8ce7f162.

Reason for revert: Introduces chance for signed integer overflow

Original change's description:
> Allow 64-bit offsets for raw_ptr arithmetic on 32-bit platforms
>
> BRP relies on operators +=/-=/+/- to verify that the new pointer doesn't
> escape the allocation slot, otherwise ref-count of another slot may get
> manipulated, leading to a byspass. Sadly, those operators were disabled
> for 64-bit offsets on 32-bit platforms.

> Thanks tsepez@ for catching that!
