re PR tree-optimization/69209 (ICE at -Os and above on x86_64-linux-gnu (verify_gimple failed))
PR tree-optimization/69209
* ipa-split.c (split_function): If split part is not
returning retval, retval has gimple type but is not
gimple value, force it into a SSA_NAME first.
* gcc.c-torture/compile/pr69209.c: New test.
