error[E0204]: the trait `Copy` may not be implemented for this type

Fixrust-lang#89137.…from_ref, r=dtolnay
Stabilize `{slice,array}::from_ref`
This PR stabilizes the following APIs as `const` functions in Rust `1.63`:
```rust
// core::array
pub const fn from_ref<T>(s: &T) -> &[T; 1];
// core::slice
pub const fn from_ref<T>(s: &T) -> &[T];
```
Note that the `mut` versions are not stabilized as unique references (`&mut _`) are [unstable in const context].

[unstable in const context]: rust-lang#57349add cast kind of from_exposed_addr (int-to-ptr casts) This is basically the dual to rust-lang#97582, for int2ptr casts. Cc `@tmiasko` rust-lang#97649
…-obk take back half-baked noaliasing check in Assignment Doing an aliasing check in `copy_op` does not make a ton of sense. We have to eventually do something in the `Assignment` statement handling instead.

On E0204 suggest missing type param bounds
