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.

multishift conjugate gradient added and a strong test: take a diagonal but non-identity matrix l1 0 0 0 .... 0 l2 0 0 .... 0 0 l3 0 ... . . . . . . . . . And apply the multishift CG to it. Sum the poles and residues. Insist that this be the same as the exactly taken square root where l1,l2,l3 >= 0.

Changes to remove warnings under icc; disambiguate AVX512 from IMCI correctly and drop swizzles in AVX512. Don't know why these compiled.
