`LessThanComparable` and `EqualityComparable` don't correspond to NaN.

Original proposed resolution:

Apply `concept_map` to these concepts at `FloatingPointType`.

[ Post Summit, Alisdair adds: ]

> I don't understand the proposed resolution - there is no such thing as a 'negative' concept_map, and these concepts are auto concepts that match float/double etc. Also not clear how we are supposed to match values to concepts.

> Recommend NAD and treat as a subset of issue 902.

Proposed resolution:

Recommend NAD.
