Remove obsolete IBM VisualAge / XL C++ workarounds in googletest

Browse Source 
Classic IBM XL C/C++ (__IBMCPP__) only supported up to C++14 (V16.1 for AIX) before IBM retired the proprietary frontend and transitioned to IBM Open XL C/C++ (which is Clang-based and defines __clang__).

Since the legacy XL frontend never supported C++17, the workarounds are obsolete and should be removed.
