Execution tests for the 'modf' builtin function

T is f32 or f16 or Type.abstractFloat
@const fn modf(e:T) -> result_struct
Splits |e| into fractional and whole number parts.
The whole part is (|e| % 1.0), and the fractional part is |e| minus the whole part.
Returns the result_struct for the given type.

S is f32 or f16 or Type.abstractFloat
T is vecN<S>
@const fn modf(e:T) -> result_struct
Splits the components of |e| into fractional and whole number parts.
The |i|'th component of the whole and fractional parts equal the whole and fractional parts of modf(e[i]).
Returns the result_struct for the given type.
