Fix PR81360

[Jan Hubicka]

Hi,
this testcase triggers ICE because we try to inline into -O0 function.
Fixed thus.

Bootstrapped/regtested x86_64-linux, comitted.

        * gcc.c-torture/compile/pr81360.c: New testcase.
        * ipa-inline.c (can_inline_edge_p): Also check that caller is optimized
