Hashing "object identities"

[Faré]

1- Case where objects are mutable. Add an integer slot "id"
initialized from (generate-id) which increments a per-thread counter
(until it reaches end of block, then get a new block).
2- Case where objects are immutable. Add an integer slot "hash"
computed from the hashes of the slot hashes, using BLAKE2.
