For occasional hotspots where naked integers are essential for
performance, wouldn't the easiest solution be to use the equivalent of
GHC's unboxed ints: a special _non-polymorphic_ datatype that doesn't
have tags. This type would be given a kind different from other types to
prevent it from being used as a type parameter. Of course the GC still
needs to be prevented from following such values, but a separate stack
for them ought to do the trick.
