Build Identifier:

NULL literal support has recently been added but we discovered that using it within a IN or a BETWEEN may invalid the query.
Maybe others are impacted.

Reproducible: Always

Steps to Reproduce:

In mclient, the following queries produce unexpected results:

1. sql>select null in (null);
   TypeException:user.s14_2[4]:'calc.==' undefined in: X_7:bit := calc.==(X_5:void,X_6:void);
   program contains errors

2. sql>select null in (1);
   types tinyint(8,0) and any(0,0) are not equal

3. sql>select null between null and null;
   TypeException:user.s18_2[4]:'calc.>=' undefined in: X_8:bit := calc.>=(X_6:void,X_7:void);
   program contains errors

Expected Results:

I think that all of the queries should return NULL.
