This would need to be a WARN or a FIXME, unless you ensure that it can
never happen in the front-end.

I think it shouldn't be necessary to copy the data,
shader->frontend_data should stay alive until the shader is destroyed.

"Unexpected immediate constant buffer size %u.\n" sounds more natural
to me, but it's not a big deal.
