Zoltan Borok-Nagy 545e60f832 IMPALA-5191: Standardize column alias behavior ...

We should not perform alias substitution in the
subexpressions of GROUP BY, HAVING, and ORDER BY
to be more standard conformant.

=== Allowed ===
SELECT int_col / 2 AS x
FROM functional.alltypes
GROUP BY x;

SELECT int_col / 2 AS x
FROM functional.alltypes
ORDER BY x;

SELECT NOT bool_col AS nb
FROM functional.alltypes
GROUP BY nb
HAVING nb;

=== Not allowed ===
SELECT int_col / 2 AS x
FROM functional.alltypes
GROUP BY x / 2;

SELECT int_col / 2 AS x
FROM functional.alltypes
ORDER BY -x;

SELECT int_col / 2 AS x
FROM functional.alltypes
GROUP BY x
HAVING x > 3;

Some extra checks were added to AnalyzeExprsTest.java.

I had to update other tests to make them pass
since the new behavior is more restrictive.

I added alias.test to the end-to-end tests.

Cherry-picks: not for 2.x.
