Actually I think it might be better not to create arrays but instead just extend DECL_GIMPLE_REG_P to types besides vector and complex ones. This way the only pass that needs to run afterwards is pass_update_address_taken and that automatically converts back non renamable variables to renamed ones without worrying about running SRA (or a special case of SRA) again.
