Ippokratis Pandis e1ae5fe95a IMPALA-1068: COMPUTE STATS should place -1 in #NULLs ...

With IMPALA-1033 we disabled the counting of the number of NULLs in each column,
and that gave a 2x speed-up in the computation. But erroneously the value 0 was
being placed in the number of NULLs, instead of the correct -1 that indicates
'unknown'.
