Using MSVC (on Windows), _Py_TYPEOF() prefers decltype() over __typeof__() on C++. Fix also _Py_TYPEOF() usage in Py_CLEAR() and Py_SETREF() macros. Replace "_Py_TYPEOF(dst)*" with "_Py_TYPEOF(&(dst))". In C++, "_Py_TYPEOF(dst)*" can fail with a compiler error. (cherry picked from commit bba99f2)
On C++, do not use decltype() in _Py_TYPEOF since it produces invalid code in Py_CLEAR() and Py_SETREF(). Instead, implement Py_CLEAR(), Py_SETREF() and Py_XSETREF() using "auto" on C++11 and newer. Add Py_CLEAR(), Py_SETREF() and Py_XSETREF() tests on an array. (cherry picked from commit 3330712)
