There are several bugs that fail in the exact same place, because
we're not able to generate code for some induction variable containing
a phi node in their evolution.  I'm trying to fix all these bugs by
implementing an analysis phase that will filter out all the difficult
loops for which we know we won't be able to generate code for.
