Not really shaken out to my satisfaction though as I want more tests done, so don't declare as working.
But committing my current while I try a few experimentals.

Partial optimisation; comms in x-dir for red black dslash will be slow as the checker skipping block strided
...
loops are non threadable. Will need to write a kernel for these instead and drive them with a lookup table
to make a look sufficiently simple to thread.

Bug fix for spread out in x (EO) direction.

This is really annoying -- it is very hard to thread the loops with the index
recursion on buffer offset in the red-black case. Must think of a good threading
solution here.
