Eric Hanson commented on HIVE-5895:
-----------------------------------
For division only, consider doing a final pass over the vector and count the
infinity values. If it is 0, do nothing. This is the common case.
If it is non-zero, then do another pass and conditionally convert the
infinities to NULL.
This avoids an if/else check in the inner loop for the common case.
