fast_distance - Vector distance.
float fast_distance(floatn p0, floatn p1);
Returns fast_length(3clc)(p0 - p1).
Built-in geometric functions operate component-wise. The description is per-component. floatn is float, float2, float3, or float4 and doublen is double, double2, double3, or double4. The built-in geometric functions are implemented using the round to nearest even rounding mode.
The geometric functions can be implemented using contractions such as mad(3clc) or fma(3clc).
