adbc7c1188 Adding files for multiple implementations (cache opt) and Ls vectorisation
of the 5D cayley form chiral fermions for the 5d matrix. With Ls entirely
in the vector direction, s-hopping terms involve rotations.

The serial dependence of the LDU inversion for Mobius and 4d even odd
checkerboarding is removed by simply applying Ls^2 operations (vectorised
many ways) as a dense matrix operation.

This should give similar throughput but high flops (non-compulsory flops)
but enable use of the KNL cache friendly kernels throughout the code.

Ls is still constrained to be a multiple of Nsimd, which is as much as 8 for AVX512
with single precision.

6d58cb2a68 Enable reordering of the loops in the assembler for cache friendly.
This gets in the way of L2 prefetching however. Do next next link in stencil
prefetching.

55f65b81b5 Improvements to the assembler interface that let us move chunks of the
site and s loop into the kernels. This will save on function call overhead and
guarantee L2 prefetching strategy is right since OMP can't distribute the
sub-chunks of work.
