[Vm-dev] Speedcenter setup

One issue we might want to discuss is the selection and sizing of the
benchmarks.

All benchmarks are autosized to run at least 600ms right now, and then
those 600ms runs are repeated up to 100 times to obtain measurements. But
600ms might be too short for some benchmarks, if the GC only kicks in
rarely for them, I don't know.

About the selection of benchmarks, the ToolInteraction went up, but that is
a very high level benchmark, and might also be influenced heavily by
refactorings in Morphic. So maybe the benchmark isn't all that useful, or I
should stop tracking trunk with the benchmark images, and instead stay on
the release.

What do you think?
