This test failure is caused by difference in IR ordering when compiling at
C++98 vs C++11
Because there was a CHECK-NOT between the two CHECKs, just changing the CHECKs
to CHECK-DAG would not work.
So to make FileCheck more flexible.
I have changed the CHECK to CHECK-DAG.
I have changed CHECK-NOT to go under a new check-prefix CHECK2 so they are
CHECK2-NOT.
