ruby: add a prefetcher
This patch adds a prefetcher for the ruby memory system. The prefetcher is based on a prefetcher implemented by others (well, I don't know who wrote the original). The prefetcher does stride-based prefetching, both unit and non-unit. It obseves the misses in the cache and trains on these. After the training period is over, the prefetcher starts issuing prefetch requests to the controller.
