0403cb3012 Always provide the BTREE_BULKLOAD hint, even when SQLITE_ENABLE_CURSOR_HINTS 
is not defined, as that hint gives a 4% performance increase.

versions of SQLite.  This side-effect of cache_size is undocumented, but 
apparently it does get used and its absence from 3.8.11 was causing problems.
