There were two cache replay code exists, one for cache replay from swift-frontend, the other for replay using C API from libSwiftScan. It is easy to forget to update one copy when new specialized cache replay logic is added for some output kinds. Now unify the replay logics to a single location to avoid confusion. This is a rewrite of the existing logic and NFCI.
