This was mentioned on http://gcc.gnu.org/ml/gcc/2011-10/msg00422.html .  So
there are two ways of fixing this bug.
Way #1: Fix ifcvt on the tree level to produce MAX_EXPR instead of the
COND_EXPR.

Way #2: Simplify COND_EXPR to MAX_EXPR during expanding or some other time.

I want to say way #1 is the correct fix.
