Russ Cox 63d531a83e dashboard: build most recent revision first
Will fill dashboard down the screen instead of up
when builders get stuck and resume.  Already live.

Also delete dead benchmark code.
I think it is safe to say that if/when we bring
benchmarks back, we will use a different
data model.

Fixes #1228.
