also, isize::MIN is an impossible distance
I'm not sure why I ever thought that would be okay. This is clearly hot code, and should avoid Array.prototype.map when it's not needed.

…Amanieu offset_from, offset: clearly separate safety requirements the user needs to prove from corollaries that automatically follow By landing rust-lang#116675 we decided that objects larger than `isize::MAX` cannot exist in the address space of a Rust program, which lets us simplify these rules. For `offset_from`, we can even state that the *absolute* distance fits into an `isize`, and therefore exclude `isize::MIN`. This PR also changes Miri to treat an `isize::MIN` difference like the other isize-overflowing cases.
