Ensure `swap_nonoverlapping` is really always untyped This replaces #134954, which was arguably overcomplicated. ## Fixes #134713 Actually using the type passed to `ptr::swap_nonoverlapping` for anything other than its size + align turns out to not work, so this goes back to always erasing the types down to just bytes. (Except in `const`, which keeps doing the same thing as before to preserve `@RalfJung's` fix from #134689) ## Fixes #134946 I'd previously moved the swapping to use auto-vectorization *on bytes*, but someone pointed out on Discord that the tail loop handling from that left a whole bunch of byte-by-byte swapping around. This goes back to manual tail handling to avoid that, then still triggers auto-vectorization on pointer-width values. (So you'll see `<4 x i64>` on `x86-64-v3` for example.) |
