WT-2729 Focus eviction on the largest trees in cache. (#2832)
Randomize visits to trees that use a tiny fraction of the cache.
Other general eviction optimizations.
Now that we are queuing more entries (potentially), make sure enough of
them become candidates. Previously, a skewed distribution of read
generations could mean that only 10% of queue entries were considered.
Improve the efficiency of sorting the queue by calculating the score
once when pages are added to the queue.
Add a workload to exercise differential eviction from trees.
In order to do that, add range partitioning to wtperf.
Don't override icount in wtperf workloads with random_range set.
