// core::ptr

impl<T: ?Sized> NonNull<T> {
    pub const fn from_ref(r: &T) -> Self;

    pub const fn from_mut(r: &mut T) -> Self;
}

Add `from_ref` and `from_mut` constructors to `core::ptr::NonNull`.

Relevant tracking issue: rust-lang#130823

The `core::ptr::NonNull` type should have the convenience constructors `from_ref` and `from_mut` for parity with `core::ptr::from_ref` and `core::ptr::from_mut`.

Although the type in question already implements `From<&T>` and `From<&mut T>`, these new functions also carry the ability to be used in constant expressions (due to not being behind a trait).
