TLB simulator fails to add tag,pid pair lookup to parent methods
For #1738 I'm adding a hashtable to speed up cache tag location for high-associativity caches. Looking at the TLB simulator to see how this change impacts it: it seems broken today, since it imposes the pair of tag,pid as the new lookup key, yet only overrides simulator_t::request! It seems like invalidate(), contains_tag(), and propagate_eviction() are all just broken for the TLB simulator since they only look up the tag?
