Tim Armstrong d37bf390a8 IMPALA-2406: avoid rows with no tuples 
In some cases the planner generated plans with rows with no
materialized tuples. Recent changes to the backend caused these to
hit a DCHECK. This patch addresses one case in the planner where it
was possible to create such plans: when the planner generated an
empty node from a select subquery with no from clause. The fix is to
create a materialized tuple based on the select list expressions, in
the same way as we handle these selects when the planner cannot
statically determine they have no result rows.

An example query is included as a test.

It also adds additional checks to the frontend and backend to catch
these invalid rows earlier.
