...with that we get the original ICE in PR84325 back:

It looks like we shouldn't skip the evaluation when ALLOW_NON_CONSTANT is
false, similarly to the CONSTANT_CLASS_P case:

We have
(unsigned int) (long int) *(const long int &)
and cxx_constant_value -> maybe_constant_init_1 doesn't evaluate it now:
