Quick-fix DebugInfo build on Windows

MSVC can't comprehend
  template<typename T, size_t N>
  ArrayRef<T> makeArrayRef(const T (&Arr)[N]) {
    return ArrayRef<T>(Arr);
  }
if Arr is
  static const uint8_t sizes[];
declared in a templated and defined a few lines later.

I'll send a proper fix (i.e. get rid of unnecessary templates) for review soon.
