--- Comment #40 from cand at gmx.com ---
I remembered where IBM's example is probably from, databases. There you could
find a stream of 7-bit ints. VSX would need adjusting between every 128-bit
block, less often than our setup, but the three vector-variable-shift instrs
there have a dependency on each other. Our unpack phase can go in parallel. So
we won't lose in speed per clock too much, even if databases aren't a major
usage point for libresoc.
