Yes. I think it uses LLVM JIT infrastructure internally which is the one responsible __jit_debug_register_code call.

It should be quite similar with the one I have linked though. Have just noticed that I had another old local patch to enable debug info for opencl:

diff --git a/gdb/testsuite/lib/opencl_hostapp.c b/gdb/testsuite/lib/opencl_hostapp.c

     strcpy (kernel_build_opts + strlen (kernel_build_opts),

With this change you may be able to trigger a pending breakpoint on the kernel function.
