Not to forget my mandelbulber bug 82717.

It was actually working with funfunctor's partial image support found at
https://cgit.freedesktop.org/~funfunctor/mesa/log/?h=clover-image-support-enabled

Currently it fails on llvm-svn 293174 with

OpenCL Build log:       <unknown>:0:0: in function fractal3D void
(%struct.sClPixel addrspace(1)*, %struct.sClInBuff addrspace(1)*,
%struct.sClInConstants addrspace(2)*, %struct.sClReflect addrspace(1)*,
%opencl.image2d_ro_t.0 addrspace(2)*, i32): unsupported call to function
get_global_id

but since it's already been working with this non-mainlined code, it's one that
can be crossed off the list maybe very soon already.
