Vlad Berindei cfc3952a83 IMPALA-898: Support explicit column names in WITH-clause views. ...

Example:
WITH t(c1, c2) AS (SELECT int_col, bool_col FROM functional.alltypes)
SELECT * FROM t

This will create a local view with the 'int_col' and 'bool_col' columns labeled as 'c1'
and 'c2'. If the number of labels is less than the number of columns, then the remaining
columns in the local view will be labeled as the corresponding columns in the query
statement. Therefore, this is also a valid query (only 'int_col' will be labeled as
'c1'):

WITH t(c1) AS (SELECT int_col, bool_col FROM functional.alltypes)
SELECT * FROM t
