Predicate Make::Private::Steps::summaryThroughStepValue

Holds if arg flows to out using a simple value-preserving flow summary, that is, a flow summary without reads and stores.

NOTE: This step should not be used in global data-flow/taint-tracking, but may be useful to include in the exposed local data-flow/taint-tracking relations.
