Merged
Conversation
`Copy<T>` does in fact not exist. The substs on the trait_ref contain the `Self` type of the impl as the first parameter, so passing that to `implements_trait`, which then nicely prepends the `Self` type for us does not end will.

The assertions requires debug assertions inside rustc, which is probably why it didn't fire here. I tested the change locally in rust-lang/rust and it did not ICE anymore.
