Dimitris Tsirogiannis 5a6f53db16 Add partition pruning tests
The following changes are included in this commit:
1. Modified the alltypesagg table to include an additional partition key
that has nulls.
2. Added a number of tests in hdfs.test that exercise the partition
pruning logic (see IMPALA-887).
3. Modified all the tests that are affected by the change in alltypesagg.

# a simple predicate
select count(*),

---- QUERY
# This query will do a join, projecting one string col from each table.
# This is interesting because the join contains string cols which causes the scanners
# to do different memory handling.
select sum(t1.id), sum(t1.int_col),max(t1.date_string_col), max(t2.string_col)
from alltypesagg t1
inner join alltypesagg t2
on t1.id = t2.id and t1.day is not null and t2.day is not null

---- QUERY
# This query does a top-n on non-string cols. This is different because without
# string cols, scanners will handle io buffers differently. They don't need to
# be passed up the execution tree.
