In rare edge cases where IS NULL is used the minimization process can
generate an expression that's not equivilant to the original one.

Zaid Abdulla 6cbd59c6ec Implement CASE operator
This also modifies the behavior of AND/OR operators to strictly return
true/false/null whereas previously they could return the value of the
first truthy/false operand. The purpose of this change is to maintain
expression equivalency before and after minimization.
