c0007d56e9 Interleave trials in benchmark script 
This should be more of a fair A/B test so the timings aren't affected by having different load on your system when testing the two alternatives.

844ca8b6b2 benchmarking: measure and analyze scripts 
This uses wall-clock time (for now) so it's noisier than alternatives
(cachegrind, CPU perf-counters), but it's still valuable. In a future diff we
can make it use those.

`measure.py` outputs something that `analyze.py` can understand, but you can use `analyze.py` without `measure.py` too. The file format is simple:

```
$ cat measurements.txt
factory_ms_jsc_jit 13.580322265625
factory_ms_jsc_jit 13.659912109375
factory_ms_jsc_jit 13.67919921875
factory_ms_jsc_nojit 12.827880859375
factory_ms_jsc_nojit 13.105224609375
factory_ms_jsc_nojit 13.195068359375
factory_ms_node 40.4891400039196
factory_ms_node 40.6669420003891
factory_ms_node 43.52413299679756
ssr_pe_cold_ms_jsc_jit 43.06005859375
...
```

(The lines do not need to be sorted.)

Comparing 0.14.0 vs master:
