derive.pass.cpp

Change the base class of std::bad_optional_access. This is a (subtle) ABI change, and is in response to http://http://wg21.link/LWG2806, which I *expect* to be adopted in Kona. I am making this change now in anticipation, and will get it into 4.0, because (a) 4.0 is the first release with std::optional, and (b) I don't want to make an ABI-change later, when the user base should be significantly larger. Note that I didn't change std::experimental::bad_optional_access, because that's still specified to derive from std::logic_error.
