Thanks!

I've checked them all, and I think these four are still incorrect:

• NonNull::new_unchecked - Already stable in 1.34: https://doc.rust-lang.org/1.34.0/src/core/ptr.rs.html#2922
• NonNull::as_ptr - Already stable in 1.34: https://doc.rust-lang.org/1.34.0/src/core/ptr.rs.html#2940
• NonNull::cast - Not stable in 1.35: https://doc.rust-lang.org/1.35.0/src/core/ptr.rs.html#3026
• [T]::as_ptr- Already stable in 1.38: https://doc.rust-lang.org/1.38.0/src/core/slice/mod.rs.html#378

And I think the ones for AtomicUsize::new, AtomicIsize:new also need to be modified (to 1.24 I think?).
