Make nofib-style anaysis for perf/compiler
The compiler runtime tests in
perf/compiler only complain if the perf gets worse by more than 5% or 10% or whatever (varies by test).
I would love it if I could get a
nofib-analyse style comparison of these benchmarks, comparing the compiler perf before and after some patch I've made.
At the moment I simply can't do this comparison in a time-effective way.
If we could generate a log-file in the right format,
nofib-analyse might already do the job.
