> The sorter works with fixed-length tuples. The number of bytes in a tuple is
> known before execution, it is available in the query plan. However, currently
> the tuple size is treated as a member variable of the TupleSorter. Using
> Codegen to replace this member variable by a constant in sorter-ir.cc could
> speed up the quicksort phase.
