 - For self-assignments during initialization (`T v = v;`), `core.uninitialized.Assign` will not report them as uninitialized accesses (except C++ reference types), and the checks will be delayed until the first accesses of these variables; `deadcode.DeadStores` will not report them as dead stores.
