Confirmed (I think we have some dups here).  We are not able to determine
the number of iterations anymore after the vectorizer has messed with the
loop structures.

Possibly simplifying the loop guards to use multiple test and branches
instead of globbing everything into a single .. | .. | .. chain could
recover this.
