Comment at: clang/unittests/Frontend/CompilerInvocationTest.cpp:267

+  ASSERT_EQ(count(GeneratedArgs, "-fdebug-pass-manager"), 1);
   ASSERT_THAT(GeneratedArgs, Not(Contains(StrEq("-fno-debug-pass-manager"))));

Does this compile / avoid the pointer comparison?
```
ASSERT_EQ(count(GeneratedArgs, StringRef("-fdebug-pass-manager")), 1);
