Add RSA key generation to speed.cc
On a Skylake machine, the improvements to make RSA key generation
constant-time did slow things down a bit:
Before:
Did 217 RSA 2048 key-gen operations in 30231344us (7.2 ops/sec)
min: 17154us, median: 117284us, max: 518336us
Did 70 RSA 3072 key-gen operations in 30188611us (2.3 ops/sec)
min: 57759us, median: 348873us, max: 1760351us
Did 27 RSA 4096 key-gen operations in 30264235us (0.9 ops/sec)
min: 202096us, median: 980160us, max: 4282915us
After:
Did 186 RSA 2048 key-gen operations in 30021173us (6.2 ops/sec)
min: 74850us, median: 147650us, max: 407031us
Did 54 RSA 3072 key-gen operations in 30111667us (1.8 ops/sec)
min: 292050us, median: 483786us, max: 1294105us
Did 18 RSA 4096 key-gen operations in 30662495us (0.6 ops/sec)
min: 902547us, median: 1446689us, max: 3660302us
