Fix occupancy issues (1 block/SM when shuffle was on).
...
There are 16 bar.sync() registers available per *chip*, not per block, and I
was using number 8 in the shuffle code. Evidently the driver rewrites them per
SM, but does not compact their range. Good to know.

Slower, but the code is a bit simpler conceptually, and the difference will be
more than accounted for by better scheduling towards the end of the process.
