  Changed paths:
    M clang/lib/Headers/__clang_hip_libdevice_declares.h
    M clang/lib/Headers/__clang_hip_math.h
    M clang/lib/Headers/__clang_hip_runtime_wrapper.h

  Log Message:
  -----------
  Make clang HIP headers compatible with C++98

Automation to detect compiler features, such as CMake's target_compile_features,
would attempt to detect compiler features by explicitly using langugage flags.
This change ensures that the HIP headers would still work with C++98.
