Auto merge of #53033 - RalfJung:manually_dro, r=SimonSapin
unsized ManuallyDrop I think this matches what @eddyb had in https://github.com/rust-lang/rust/pull/52711 originally. ~~However, I have never added a `CoerceUnsized` before so I am not sure if I did this right. I copied the `unstable` attribute on the `impl` from elsewhere, but AFAIK it is useless because `impl`'s are insta-stable... so shouldn't this rather say "stable since 1.30"?~~ This is insta-stable and hence requires FCP, at least. Fixes https://github.com/rust-lang/rust/issues/47034
