Why should the compilers care? Aggregates layout and alignment of
integral/floating types must match between host and offload compilers, sure,
but isn't that something streamed already in the LTO bytecode?
Or is LTO streamer not streaming some types like long_type_node?
It isn't, see the preload_common_nodes code. Also, the backend needs to
choose the right Pmode (and in the case of ptx, emit a directive about
address sizes).
