/org/llvm/build? cat /tmp/s.c
__attribute__((noinline)) int f() {
  return 1;
}

int g() {
  return f() + 4;
}
/org/llvm/build? ./bin/clang /tmp/s.c -O0 -Rpass-missed=. -c
/tmp/s.c:6:10: remark: f will not be inlined into g [-Rpass-missed=inline]
  return f() + 4;
         ^
/org/llvm/build? ./bin/clang /tmp/s.c -O0 -Rpass-missed=. -c -save-temps
/org/llvm/build?


In this case EmitBackendOutput is called in CodeGenAction::ExecuteAction which
does not set up the DiagnosticHandler.
