The PR targets PDO_sqlite as well as sqlite3, so I'm changing the
package back to "SQLite related".

thanks! I just added PR to added desired behaviour but suppose that it requires proper RFC.

Description:
------------
SQLite has an option to define a custom function as deterministic, and by that allowing it to be
indexed. This obviously has a huge impact on the performance.
Adding SQLITE_DETERMINISTIC (0x800) to the 4th parameter does the trick, check this for more
information:
https://www.sqlite.org/c3ref/create_function.html
From what my basic C skills tell me, it's currently hard-coded in PHP:
https://github.com/php/php-src/blob/master/ext/sqlite3/sqlite3.c#L933
Exposing the 4th parameter would give us this flexibility.
