C++20 and C++23 make implicit destructors constexpr when possible, and compiler changes make this happen in more cases. This causes a few objects to be instantiated more eagerly which is causing template instantiation failures.

We likely need to avoid forward-declaring some types in this case, or explicitly define the destructors out-of-line to avoid the implicit destructor being instantiated too early.

LLVM PR which contains some discussion on the C++ standard changes that cause this failure: https://github.com/llvm/llvm-project/pull/77753
