This will take a little time as I don't have that much time right now, so @rustbot author

I've addressed all the comments, but #101061 will force me to change some of the intrinsics used here if it's merged. This brings me to a question: Should we use...

Yeah, this pass could be seen as a very simple MaybeUninit sanitizer. But I agree that this is quite some complexity without precedent, and I am not sure whether it's...

This would break, we guarantee it to be transparent over `T`. If I read a `T` in memory as a `MaybeUninit`, which is allowed as it's transparent, it would do...

I'm waiting for whether we want to go forward with this before I'm cleaning this up further

If we had a GAT-ified Index, you could build this on top of it with Result, Option, or anything you desire.
