- `Div` and `Rem` by their `NonZero` variant is now implemented for all unsigned integers.
- stabilization of `deque_range`
- deprecation of `spin_loop_hint`

Add `needs-asm-support` compiletest directive, and use it in asm tests
that require asm support without relying on any architecture specific
features.

Update RELEASES.md

A couple of things that were missing in the release notes:

- `Div` and `Rem` by their `NonZero` variant is now implemented for all unsigned integers (rust-lang#79134)
- Stabilization of `VecDeque::range` and `VecDeque::range_mut` (rust-lang#79022, stabilization version corrected to 1.51.0 rust-lang#80448)
- Deprecation of `spin_loop_hint` (rust-lang#80966)

Remove `T: Debug` bound on UnsafeCell Debug impl

Prior art: rust-lang#65013

…trailing_zeros, r=m-ou-se

Stabilize nonzero_leading_trailing_zeros

Stabilizing nonzero_leading_trailing_zeros and due to this also stabilizing the intrinsic cttz_nonzero

Check for asm support in UI tests that require it

Add `needs-asm-support` compiletest directive, and use it in asm tests
that require asm support without relying on any architecture specific
features.

Closes rust-lang#84038.
