aphadke c671ee1ece IMPALA-4738: STDDEV_SAMP should return NULL for single record input 
In calculating the STDDEV_SAMP/VARIANCE of N rows a divion by
N-1 rows is involved. Hence STDDEV_SAMP/VARIANCE for a single
row involves a division by 0. This change returns a NULL instead
of a 0 when calculating STDDEV_SAMP/VARIANCE for a single row.
STDDEV_POP/VARIANCE_POP for single row will still return a 0 since
this does not involve  a division by 0. This matches the postgres
behavior.
