There is a lot of boilerplate across Unsafe{Raw}{Mutable}Pointer that can instead be done via protocol extensions on the already-existing _Pointer protocol, since it's all identical and only relies on access to the underlying builtin pointer. This reduces the actual code to the point where it makes sense to de-gyb the file. Since most of this code is transparent anyway, it should make little difference to performance.

More code could be shared via the introduction of additional protocols (like for mutable pointers) but that's probably not worth it.
