Introduce per-family instance index (#1165)
Much like it makes sense to enumerate all the families,
it makes sense to enumerate stuff within families.
Alternatively, we could have a global instance index,
but i'm not sure why that would be better.

This will be useful when the benchmarks are run not in order,
for the tools to sort the results properly.
