[PATCH 1/5] benchtests: Add exp10f benchmark

I don't see the values converted - to keep the same output range I'd do:
new_val = (float) log10 (exp ((double)old_val)). Otherwise given the larger
base I'd expect it to hit huge values and exceptional cases far more often
than the original trace, making it less relevant.

Also keeping the workload line means we get more accurate benchmark
results, including throughput and latency.

Cheers,
Wilco
