Execution tests for the 'abs' builtin function

The absolute value of e. Component-wise when T is a vector. If e is a signed
integral scalar type and evaluates to the largest negative value, then the
result is e. If e is an unsigned integral type, then the result is e.
S is AbstractFloat, f32, f16

@const fn abs(e: T ) -> T
Returns the absolute value of e (e.g. e with a positive sign bit).
Component-wise when T is a vector.
