18938 No more results on main branches

From now on, results that matter (read: round/preview output) will be stored
on branches with the appropriate names. For round 8, the branches will be called:

round8-i7-linux
round8-i7-win
round8-ec2-linux
etc

These rounds can end up having multiple commits and the results may change from
run to run
