Ok, it compiled the testcase with -fno-exceptions and even seems to run
successfully. But the vectorizer didn't do anything interesting. Not one loop
out of 323 was vectorized, mostly due to "complicated pointer arithmetic" or
"can't compute number of iterations". The interesting ones all due to the
latter reason.
