These fences were added before we decided that (1) `NativeFinalizer`s
are only attached to `Finalizable`s and (2) `Finalizer`s do not have
a guarantee against premature finalization.
Now that we're inlining, we should avoid allocating the `Pointer`
object.
TEST=Should be a no-op, running a bunch of bots just in case.
