> SqlRexConvertlets are used to transform a SqlCall into a RexCall while
> parsing a sql string. A RelNode that is created using RelBuilder does not use
> the same transformations. This causes the following error while trying to use
> RelBuilder to create a relnode that use {{{}TIMESTAMPDIFF(){}}}.
> {code:java}
> Suppressed: java.lang.RuntimeException: cannot translate call
> TIMESTAMPDIFF($t8, $t4, $t9)

> Modify RexBuilder to check if there is a convertlet that exists for the
> operator being constructed and transform the RexCall using the convertlet.
