add ideal allocation tracker

+ Kind of like CHERI, but uses out-of-line pointer information.
  The idea is that a core that is compatible with ALLOC_IF queries
  the allocation tracker if an address is legal and gets a response.
  This ideal tracker effectively has infinite memory and doesn't talk to
  any other components, but a real implementation might want to limit
  the allocations per process or chat with some reserved memory region
  somewhere else in the system to maintain a binary tree or something.
