Other IFNs should make the call non-constant.

This should be an xfail (pending the delayed folding work) instead of a
different test.
+constexpr int n3 = fn7 ((const int *) 0, 8); // { dg-error "is not a constant
expression|constexpr call flows off" }
The "flows off the end" error is a bug and should not be tested for.
I'm going to check in a fix.
