6860e6fa6f Activate the ability to use expressions in indexes in a query. There are some 
test failures, but mostly this seems to work.

1f9ca2c84c Add code to maintain indexes with expression arguments across DELETE, INSERT, 
and UPDATE statements.  Legacy tests pass, but the new code paths are still
largely untested.  The query planner currently makes no effort to use
expression indexes.

simple column names.  The sqlite3RestrictColumnListSyntax() routine is removed
