Execution tests for the 'clamp' builtin function

S is AbstractInt, i32, or u32
T is S or vecN<S>
@const fn clamp(e: T , low: T, high: T) -> T
Returns min(max(e,low),high). Component-wise when T is a vector.

S is AbstractFloat, f32, f16
T is S or vecN<S>
@const clamp(e: T , low: T , high: T) -> T
Returns either min(max(e,low),high), or the median of the three values e, low, high.
Component-wise when T is a vector.
