3844bcf800 If no f16c instructions supported must use software half precision conversion. 
This will also become useful on BG/Q, so will move out from SSE4 into a general area.
Lifted the Eigen half precision from web. Looks sensible, but not extensively regressed
against the intrinsics implementation yet.

8e161152e4 MultiRHS solver improvements with slice operations moved into lattice and sped up. 
Block solver requires a lot of performance work.

d3b9a7fa14 F16c apparently requires AVX, even if the 128 bit are used. 
Seems odd.
