Make sure this testcase keeps crashing with -O3.
Recent optimization improvements made LLVM realize the store-to-null was
unavoidable, so it deleted all of main() and replaced it with 'unreachable'.
Because the body of main() no longer even contained a return instruction,
calling it caused random code to be ran instead. This happened to be the code
that links in the ModuleInfo on my machine, which then returned "successfully".
