Subject: [Bug c++/22568] Should use cmov in some stituations

This still happens with 4.1. I also can't make it use two cmovs, by changing
the source a bit, e.g. like:
typedef unsigned long ulong;
extern ulong use (ulong, ulong);
ulong f(ulong a, ulong b)
{
ulong tmp = a;
if (a < b) {
a = b;
b = tmp;
}
return use (a, b);
}
