mem: Add support for writing back and flushing caches
This patch adds support for the following optional drain methods in the classical memory system's cache model: memWriteback() - Write back all dirty cache lines to memory using functional accesses. memInvalidate() - Invalidate all cache lines. Dirty cache lines are lost unless a writeback is requested. Since memWriteback() is called when checkpointing systems, this patch adds support for checkpointing systems with caches. The serialization code now checks whether there are any dirty lines in the cache. If there are dirty lines in the cache, the checkpoint is flagged as bad and a warning is printed.
