I'm very close to landing 'real' printf support in the GPU libc where `printf`
is just a regular function call. Will this change the handling for that in any
way? I've already had to make the backend pass respect `-fno-builtins` and
remove `ockl` from OpenMP to make that possible so I'm hoping we don't end up
with a lot more special casing for `printf`.
