Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables
with the assumption that such tables really contain 10 elements. This gives
better query plans for tables that are truely empty, but is likely to cause
problems in legacy systems, so the change is kept off trunk. Some TCL tests
fail on this check-in due to the new stat1 entries.
