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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204335 91177308-0d34-0410-b5e6-96231b3b80d8
