-- TODO: Return this test after simplifying InterpreterSelectQuery TODO: Tautological optimization breaks JIT expression compilation, because it can return constant result
for non constant columns. And then sample blocks from same ActionsDAGs can be mismatched.
This optimization cannot be performed on AST rewrite level, because we does not have information about types
and equals(tuple(NULL), tuple(NULL)) have same hash code, but should not be optimized.
Return this test after refactoring of InterpreterSelectQuery.
