error[E0080]: evaluation of constant value failed
Stabilize `const_raw_ptr_deref` for `*const T` This stabilizes dereferencing immutable raw pointers in const contexts. It does not stabilize `*mut T` dereferencing. This is placed behind the `const_raw_mut_ptr_deref` feature gate.

Remove the const_raw_ptr_comparison feature gate. We can never supply a meaningful implementation of this. Instead, the follow up commits will create two intrinsics that approximate comparisons: * `ptr_maybe_eq` * `ptr_maybe_ne` The fact that `ptr_maybe_eq(a, b)` is not necessarily the same value as `!ptr_maybe_ne(a, b)` is a symptom of this entire problem.
