For testing, it can be useful to simulate an enormous amount of memory (e.g. 2^64 RAM). This adds an MMIO device that acts as sparse memory. When something writes a nonzero value to a sparse-mem address, we allocate a block of memory. For now, since the only user of this device is the fuzzer, we do not track and free zeroed blocks. The device has a very low priority (so it can be mapped beneath actual RAM, and virtual device MMIO regions).
