      In SERVER-95112, we introduced PlanStageKey to represent an identifier for a PlanStage which could be used in a map. It was typedef'd to PlanStage*, but the intention was to never dereference this pointer, as this key may outlive the PlanStage itself. The compiler currently will not warn on accidently dereferencing this type.

      We can improve this by making PlanStageKey an uint64_t.
