The tests added as part of 9fdb675fc5 yield differing results
depending on endianess, causing buildfarm failures. As the differences
are expected, split the hash partitioning tests into a different file
and maintain alternative output. The separate file is so the amount of
duplicated output is reduced.
David produced the alternative output without a machine to test on, so
it's possible this'll require a buildfarm cycle or two to get right.
