[clang] Exclude invalid destructors from lookups. This fixes a crash when declaring a destructor with a wrong name, then writing result to pch file and loading it again. The PCH storage uses DeclarationNameKey as key and it is the same key for both the invalid destructor and the implicit one that was created because the other one was invalid. When querying for the Foo::~Foo we end up getting Foo::~Bar, which is then rejected and we end up with nullptr in CXXRecordDecl::GetDestructor().
