Feature/cg reliable update

Stability improvement to BCG. Force m_rr hermitian beyond rounding.

Staggered multinode block cg debugged. Missing global sum.
...
Code stalls and resumes on KNL at cambridge. Curious.
CG iterations 23ms each, then 3200 ms pauses. Mean bandwidth reports
as 200MB/s. Comms dominant in the report. However, the time behaviour suggests it
is *bursty*.... Could be swap to disk?

Added switching to fallback linear operator in reliable update CG, and added recalculation of b parameter on update.

Block solver complete for staggered. Now stable on mass 0.003 and
...
gives 8x (!) speed up on Haswell laptop vs. standard CG for 8 RHS solves.
166 iterations vs. 537 iterations so algorithmic gain + 2x in flop rate gain.
Better than a slap in the face with a wet kipper.
