+0000 Subject: [PATCH 17/48] Codegen storage markers as assignments to __CPROVER_dead_object This changes our handling of storage markers to be marking is-alive only rather than treating StorageLive as creating a new object. That is, object instances are now tied to their Mir-provided declarations (which, at present, only appear once per function). To still account for when Rust scopes deem an object to be alive, we use StorageLive and StorageDead to update `__CPROVER_dead_object`. This (global) variable is used by CBMC's pointer checks to track when a pointer may not be safe to dereference for it could be pointing to an object that no longer is in scope.
