mem: mmap the backing store with MAP_NORESERVE
This patch ensures we can run simulations with very large simulated memories (at least 64 TB based on some quick runs on a Linux workstation). In essence this allows us to efficiently deal with sparse address maps without having to implement a redirection layer in the backing store. This opens up for run-time errors if we eventually exhausts the hosts memory and swap space, but this should hopefully never happen.
