Hand unrolled version of dslash in a separate class.
...
Useful to compare; raises Intel compiler from 9GFlop/s to 17.5 Gflops.
on ivybridge core. Raises Clang form 14.5 to 17.5

Got unpreconditioned conjugate gradient to run and converge on a random (uniform random,
...
not even SU(3) for now) gauge field. Convergence history is correctly indepdendent of decomposition
on 1,2,4,8,16 mpi tasks.
Found a couple of simd bugs which required fixed and enhanced the Grid_simd.cc test suite.
Implemented the Mdag, M, MdagM, Meooe Mooee schur type stuff in the wilson dop.

Getting closer to having a wilson solver... introducing a first and untested
...
cut at Conjugate gradient. Also copied in Remez, Zolotarev, Chebyshev from
Mike Clark, Tony Kennedy and my BFM package respectively since we know we will
need these. I wanted the structure of
algorithms/approx
algorithms/iterative
etc.. to start taking shape.

Threading support rework.
...
Placed parallel pragmas as macros; implemented deterministic thread reduction in style of
BFM.

Small tweak to enable benchmarking to suppress gauge field bandwidth as a test.

This is a short term hack while I benchmark.

Fixed the stencil sector and Wilson now agrees between stencil based implementation
...
and the cshift based implementation. Managed to reduce the volume of code in this
sector a little, but consolidation would be good, perhaps taking common
logic out into simple helper functions

Shaken out stencil to the point where I think wilson dslash is correct.
...
Need to audit code carefully, consolidate between stencil and cshift,
and then benchmark and optimise.
