c++: Add test for DR 1423, Convertibility of nullptr to bool.
DR 1423, which supersedes DR 654, says that you can't copy-init
a bool from a std::nullptr_t:
bool b = nullptr; // error
Conversely, it works with direct-initialization which is more
permissive than copy-initialization.
No code changes necessary since we handle it right.
