properly When the optimizer rewrites conjunct exprs with constant values, a new expr may cause AnalysisException. In this case, the conjuncts should use the original expr, not the intermediate expr produced by propagateConstants. Fixed optimizeConjuncts to handle this scenario properly. Tests: Add unit test for alias. Ran exhaustive tests.
