Gilles Peskine 28f62f6212 Support running the benchmark with a single curve 
If you pass a curve name to the benchmark program, the ECDH and ECDSA
benchmarks will only run for that particular curve. By default, all
curves are benchmarked.

To simplify the implementation, if you pass multiple curves, only the
last one will be benchmarked.
