   3 # Naive clusterization mainly groups by instruction opcode,
   4 # but it should also partition the benchmarks of the same opcode
   5 # by the sched class. For example, a regular `xor`, and same-operand `xor`
   6 # may have different characteristics, and it will be confusing/misleading
   7 # to group them.
