Re: motion: update exception and flag operations for consistency

By having these functions (and the other ones you proposed)

How could they fail? Conforming implementations (there's a predicate to
test that) must provide them.
These functions concern signaling exceptions and raising flags as defined
in 754R glossary. These are not Unix signals. The functions I
defined have no failure modes.
If these functions are added to a general purpose language, such as C,
then they need to work in environments where the floating-point is
not IEEE-754 (such as IBM S/360 hex FP, or VAX FP). In those environments,
these functions could fail.
