Michael Ho resolved IMPALA-6184.
--------------------------------
       Resolution: Fixed
    Fix Version/s: Impala 2.11.0

Fixed at https://github.com/apache/incubator-impala/commit/3ddafcd29505614a01c8f4362396635c84ab4052

IMPALA-6184: Clean up after ScalarExprEvaluator::Clone() fails
When ScalarExprEvaluator::Clone() fails, the newly created evaluator was
not added to the output vector. This makes it impossible for callers to
close and clean up the evaluators afterwards. This change fixes this by
always adding the newly created evaluator to the output vector before
checking for the error status.

This path is only exercised in the scanner code. Two new tests are added
to exercise the failure paths.

Testing done: newly added tests in udf-errors.test
