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.

The macro “magics” is very intensive for the preprocessor in the measurement code which has numerous serialisable classes. Reducing the number of serialisable fields to 64 (instead of 1024) helps a lot, this is enough for now and can be extended trivially if needed in the future.
