Thanks.

While changing this part, it can be rewritten using dg-additional options, e.g.:

/* { dg-options "-Os -fomit-frame-pointer -fasynchronous-unwind-tables
-mno-red-zone" } */
/* { dg-additional-options "-mpreferred-stack-boundary=3" { target ia32 } } */

Since Jakub mentioned branching today, and I wasn't sure I'd have time 
for a retest, I've committed it as-is.
