Seems to work both ways?
Sure, but you're pointlessly memmove-ing memory over itself. I'm not
sure how many segments a single memory region will usually have, but
it's better to be safe.
This will never be an issue in practice. We expect to have few
FlatRanges (O(100)), simplify() will be called very rarely (never during
normal operations; a few dozen times during boot; a few during hotplug);
everything is in L1 cache; and the cost will be dwarfed by any calls to
kvm (if enabled).
