I'm testing a patch that would fix both this PR and PR33834 (posted it under
the PR33834 entry). By the way, this testcase does not get vectorized with
current mainline (an Oct21 snapshot) because the call to cos is not taken out
of the inner-loop, although it's invariant; it was taken out of the loop with
an older snapshot (Sept10). Another data point - in the testcase in PR33834 the
call to cos is taken out of the inner-loop with current snapshot.
