Henry Robinson f22b8659fd IMPALA-1595: Add 'location' to SHOW [TABLE STATS|PARTITIONS] for HDFS tables 
This patch adds a 'location' column to the output of SHOW TABLE STATS /
SHOW PARTITIONS. This helps users understand the effects of ALTER TABLE
SET LOCATION commands, particularly for partitions, and is easier to
identify than the output of DESCRIBE FORMATTED.

Some existing tests in alter-table.test have been updated to include
checking the location output before and after a SET LOCATION
command. The tests in show.test have also been updated to check for the
location; all other tests that use SHOW [TABLE STATS|PARTITIONS] use a
generic regex to avoid overly verbose tests.
