TARGET_PRESERVE_RELOAD_P is a hook that is defined by a local patch
we got.  This is merely an optimization, so the only issue with that
piece of infrastructure missing is a warning for the unused hook
function, and a bit worse code.  Maybe.  Once the lra dust has
settled, and the port is in, I'll have to check if the patch is still
applicable and suitable.
