The percentage of the total CC graph that was collected is a handy way to judge the efficiency of a cycle collection at a glance.

Attachment: Add cycle collector efficiency to COLLECT_TIME_DEBUG logging.

I changed this to only show the percentage when there are at least 1000 things in the graph, because I don't care how efficient tiny CC graphs are, in particular the worker CCs.
