Docs: https://docs.google.com/document/d/13n1qaB6A-gvgWc9NDhWm-UPuOqow_Y0DNgCeTbtIotI Modify that C++ backend so that it can emit either runtime C++ or postmortem debugging code. When in postmortem debugging mode, the overall code structure would look similar with some difference: 1. Instead of passing an Isolate* everywhere, we pass a MemoryAccessor. 2. Instead of runtime class names like String, we use uintptr_t 3. When loading data from objects, instead of TaggedField<T>::load or Object::ReadField (which read from the current process), we use the MemoryAccessor and read data from the debuggee process. 4. Return values should be wrapped in the Value struct. Implement the debug accessors for complex length expressions and add test for such class (SmallOrderedHashSet).
