IMPALA-11766: In buildBinaryStatsPredicate, an Expr needs to be cloned
The following code in buildBinaryStatsPredicate has a potential bug:
// Obtain the rhs expr of the input predicate
Expr constExpr = inputPred.getChild(1);
...
BinaryPredicate statsPred = new BinaryPredicate(op, slot, constExpr);
The constExpr is mutable and the "new BinaryPredicate" can change
the object. If it does, it could have an adverse effect on inputPred.
