Peter Toth 418f7dc973 [SPARK-30447][SQL] Constant propagation nullability issue ... ## What changes were proposed in this pull request? This PR fixes `ConstantPropagation` rule as the current implementation produce incorrect results in some cases. E.g. ``` SELECT * FROM t WHERE NOT(c = 1 AND c + 1 = 1) ``` returns those rows where `c` is null due to `1 + 1 = 1` propagation but it shouldn't. ## Why are the changes needed? To fix a bug. ## Does this PR introduce any user-facing change? Yes, fixes a bug. ## How was this patch tested? New UTs. Closes #27119 from peter-toth/SPARK-30447.
