paboyle 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.
