IPA: support -flto + -flive-patching=inline-clone
There's no fundamental reason why -flive-patching=inline-clone can't
coexist with -flto. Yes, one can theoretically have many more clone
function that includes a live patch. It is pretty much the same
as in-module inlining.
gcc/ChangeLog:
* opts.cc (finish_options): Print sorry message only
for -flive-patching=inline-only-static.
gcc/testsuite/ChangeLog:
* gcc.dg/live-patching-2.c: Update scanned pattern.
* gcc.dg/live-patching-5.c: New test.
