benchmark: add --track to benchmark

Browse source 
This option will measure how long the benchmark
takes to run. Example:

```
$ ./node benchmark/run.js --track assert

assert/assertion-error.js
assert/assertion-error.js size=2 n=200: 22,987.24012781365
assert/assertion-error.js size=75 n=200: 296.2362823364434
[740ms] assert/assertion-error.js

...
```
