It's just to clean up unnecessary alloca's and focus the test on the varargs code.

I've switched it down to –O1 in r218298.

Why are you running the optimizer at all? This is a test for the code generation of the frontend producing the correct IR, not a test of the optimizer?

If you want to test how the optimizer behaves with a specific set of annotations on IR, that belongs in LLVM's test suite.
