I don't think this is a good idea.  The C API is stable, so this would
lock down the list of attributes as well.  I think that makes this patch
a no-go.

Even exposing the data layout string seems dangerous, although maybe
there's precedent here from `lto_module_get_target_triple()`?

Rafael, am I missing something here?
