[Bug c++/115670] auto placeholder for return type should change the linkage of the function if the type becomes local linkage too

--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So at -O1, foo0, foo5, foo6 are the only ones left.

at -O0, foo1, foo2, foo3, foo4 are also emitted but that is expected since GCC
emits static unused functions always at -O0.


So let's keep this for foo0/foo5. I will file one for foo6 in a second.
