mem: add CacheVerbose debug flag, filter noisy DPRINTFs
Some of the DPRINTFs added to the classic cache in cset 45df88079f04, while useful to those unfamiliar with the cache code, end up being noise when you're familiar with the code but are trying to debug tricky protocol issues. (Particularly getting two messages from each cache as it receives a snoop request then declares that there was no match.) This patch introduces a CacheVerbose debug flag, and moves a subset of the added DPRINTFs into that category, so that Cache by itself returns to being a more succinct summary of cache activity. Also added a CacheAll compound flag to turn on all the cache-related debug flags (other than CacheTags, which you *really* have to want badly to turn it on, IMO).
