Fix errors from building with clang-20.

The issues were:

  • Using memcpy with non-trivial structs became warn-as-error.
  • our "safe to return" pattern breaks in constexpr in C++11 mode and clang-20 updated their intrinsics headers to make intrinsics constexpr. Include the intrinsics headers before we ever include debugreturn.h
