Fix a leak found by LSan: ConsumedBlockInfo owns its StateMapsArray entries.

(I tried converting StateMapsArray to a vector<unique_ptr> and changing the
types of getInfo() and addInfo() to take unique_ptrs.  This mostly worked,
except for the three-argument form of addInfo() which I found confusing enough
that I went with this simpler fix for now.)
