math: add Compare and Compare32
This change introduces the Compare and Compare32 functions
based on the total-ordering predicate in IEEE-754, section 5.10.
In particular,
* -NaN is ordered before any other value
* +NaN is ordered after any other value
* -0 is ordered before +0
* All other values are ordered the usual way
