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?

Simplified lanczos, added Eigen diagonalisation.
...
Curious if we can deprecate dependencly on BLAS.
Will see when we get 48^3 running on our BG/Q port

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.

Block solver requires a lot of performance work.

MultiRHS working, starting to optimise. Block doesn't and I thought it already was; puzzled.
