--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Testing the attached but I expect it'll not work as the updating in
cgraph_update_edges_for_call_stmt_node seems to expect a 1:1 "folding".

It does look fragile as hell...

I guess I'll finally go and make SSA_NAME_DEFAULT_DEF possible on anon
SSA names which means we can avoid that extra stmt in folding...
