The new OpenMP offloading currently driver embeds offloading IR directly
into the host object. This is easier to handle in the tooling, however
makes it difficult to easily inspect the output generated by the
compiler. The old method used the clang-offload-bundler tool put the IR
side-by-side. We should do something similar with the new driver to
prevent the need to use save-temps for simple cases. An example of this
is shown when using a tool like godbolt to share code:
https://godbolt.org/z/eYEcYsbs5.

This doesn't address bundling preprocessor output yet.
