> With a data set large enough to cause the external sort to spill we hit index
> out of bounds exception when we have a fixed width vector in the record
> batch. With the recent automatic memory reallocation fix (DRILL-1960) we
> moved to allocating memory for fixed width vectors with target record counts
> (instead of allocateNewSafe). However in PriorityQueueCopierTemplate we still
> use the old interface and since we don't use copyFromSafe() anymore we hit
> IOOB since the vector is not sized as expected. Fix is simply to use
> AllocationHelper so that we allocate the exact memory required by fixed width
> vectors.
