      The keys in the lookaside table can be long and all the entries for a given value share a prefix. We should enable prefix compression to get a more compact representation of lookaside entries in memory and on disk. This should be particularly noticeable for workloads with small document sizes.

      Note: this work started in WT-3769, which evolved into a bug fix for reverse cursor walks with particular delete patterns with prefix compression enabled.
