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. 2020-06-12 12:25:14 -05:00			`error[E0133]: dereference of raw pointer is unsafe and requires unsafe function or block`
