Alex Behm 12496c7fbf IMPALA-1657: Rework detection and reporting of corrupt table stats. ...

1. Minor fixes for cardinality estimation of unpartitioned tables.
2. Reworks handling of corrupt table stats as follows:
   The stats of a table or partition are reported as corrupt if the
   numRows < -1, or if numRows == 0 but the table size is positive.
3. Removes the Preconditions check reported in IMPALA-1657 in favor
   or issuing a corrupt table stats warning.
4. Fixes a few tests to set numRows together with
   STATS_GENERATED_VIA_STATS_TASK so that the numRows is definitely
   set in the HMS.
