To document the current state...

Recently I was getting "unsupported call to function get_global_id&quo=
t; so I
assumed there was some llvm problem. Turns out if this happens you just nee=
d to
rebuild libclc for your llvm version.

With these patches mandelbulber-opencl sorta works:

The rendering actually looks close to how OpenCL from amdgpu-pro renders.

Today it sorta works, but looks worse. Some comparison screenshots:
