c++: Poor diagnostic for dynamic_cast in constexpr context [PR93414]
I neglected to add a proper diagnostic for the reference dynamic_cast
case when the operand of a dynamic_cast doesn't refer to a public base
of Derived, resulting in suboptimal error message
error: call to non-'constexpr' function 'void* __cxa_bad_cast()'

PR c++/93414 - poor diagnostic for dynamic_cast in constexpr context.
* constexpr.c (cxx_eval_dynamic_cast_fn): Add a reference
dynamic_cast diagnostic.
* g++.dg/cpp2a/constexpr-dynamic18.C: New test.
