> Calcite should simplify "\{{a IN (1, 2) AND a = 1}}" to "\{{a = 1}}". Check this test in {{RexProgramTest}}:
> {code:java}
> @Test void testSimplifyInAnd() {
>     // deptno in (20, 10) and deptno = 10
>     //   ==>
>     // deptno = 10
>     final RexNode e =
>         and(
>             in(vInt(), literal(20), literal(10)),
>             eq(vInt(), literal(10)));
>     checkSimplify(e, "=(?0.int0, 10)");
