[Speed] Adapting pypy benchmark suite

[Maciej Fijalkowski]

Hi

I have a radical idea: to take a pypy benchmark suite, update the
libraries to newer ones and replace python benchmarks with that. The
main reason being that pypy has a much better coverage of things that
are not microbenchmarks, the list (in json):

Which is much more extensive than this:

https://hg.python.org/benchmarks/file/tip/performance

I'm willing to put *some* effort, what do people think?

Cheers,
