There was a problem hiding this comment.
Should we name them Vacant and Occupied like the std lib does?

Problem
LoadedPrograms::insert_entry()checks if a program exists in the cache that matches deployment and effective slot number for the given program key. It currently returns false in such cases. However, it should return an existing program entry, as that is needed for deduplication in case two transaction batches load the same program simultaneously.Summary of Changes
This PR changes the return type to an enum
LoadedProgramEntry, that conveys if the entry already existed, or was newly added. Also, it carries anArcto the valid loaded program instance.Fixes #
