We can do that in create_target_clone which calls
node->create_version_clone_with_body where a new function_decl is created.

However, the following code does not work:

  for (tree arg = DECL_ARGUMENTS (new_node->decl); arg; arg = DECL_CHAIN (arg))
    if (VECTOR_TYPE_P (TREE_TYPE (arg)))
      SET_DECL_MODE (arg, TYPE_MODE (TREE_TYPE (arg)));

I'm curious about what needs to be changed once we can get a proper MODE for
the new argument.
