Unsafe Read Beyond of Death

Cool optimization trick and I think Daniel Lemire did post something like this before. That being said, I wont be using gxhash any time soon because of how this technique when written in Rust (or even C/C++ too) it is UB even if the underlying hardware allows it. If you want to use this technique you have a few options

• Check the final ASM output (not scalable lol)
• Just write it using ASM directly
