Instead of determining the alignment based on the pointer element type (which is incompatible with opaque pointers), make use of alignment annotations added by the frontend. In particular, clang will add alignment attributes to OpenCL kernels since D118894. Other frontends might need to be adjusted to add the attribute as well.
