The change is that now the struct is dynamically initialized rather than
statically as it used to.
So it is not wrong, just worse code quality.
And the reason for that is that maybe_constant_value doesn't fold it into a
constant, because there is TREE_OVERFLOW. sizeof result is size_t, unsigned
type and TREE_OVERFLOW comes probably from - 1 at the end converted to -1U and
then converted to int.
