Backport check-ins [0900e35348f4b9bf3] and [4fead8e714c7e50] to the 3.7.2
...
branch. These check-ins provide hints to the btree layer for when it is
possible to use a hash table rather than a btree to implement an index.
The SQLite BTree layer does not use these hints, but alternative btree layers
might.
