Use the common BVH utilities header for this. Added a special type qualifier ccl_ray_data which is defined to ccl_private for all platforms but Metal. On Metal it is defined to ray_data. The tricky part is that the BVH utilities are wrapped into the Metal context class. In some of the BVH functions the context has been already constructed, but it wasn't done in all the callbacks. From a quick render tests of the Junkshop benchmark scene there is no render time difference, No functional changes are expected.
