Alexander Potapenko 90844c4778 [ASan] Add -asan-module to the ASan .ll tests.
After the -asan pass had been split into -asan (function-level) and -asan-module (module-level) some of the
tests have silently stopped working, because they didn't instrument the globals anymore.
We've decided to have every test using both passes, irrespective of the presence of globals in it.
