Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache.

Fix sqlite3ExprCompare() so that it ignores differences in the Expr.iTable field for IN operators, as otherwise it can lead to false negatives, which is usually harmless, but can cause problems for an assert() in the window function logic. check-in: 6a204b19 user: drh tags: trunk
