While working on complex lowering, I noticed that the
testcase pr42196-3.c had some interesting code in it
and most likely a copy and pasto. Since this testcase
was added back in 2009, I rather add a new testcase
rather than changing the old one.
The testcase was doing:
```
if (b)
{
f1 = __real__ u.cf;
f1 = __imag__ u.cf;
}
else
{
f1 = __real__ u.ci;
f1 = __imag__ u.ci;
}
r = bar (f1, f2);
```
I suspect the second f1 in both sides of the conditional
were supposed to be f2. So the new testcase does that.
Tested on x86_64-linux-gnu and pushed as obvious.
