As PR20495 demonstrates, Clang currenlty infers the CUDA target (host/device, etc) for implicit members (constructors, etc.) incorrectly. This causes errors and even assertions in Clang when compiling code (assertions in C++11 mode where implicit move constructors are added into the mix). Fix the problem by inferring the target from the methods the implicit member should call (depending on its base classes and fields). llvm-svn: 218624
