[Issue 2154] Correct error when building with IBM's latest XLC (#2155)
* [Issue 2154] Correct error when building with IBM's latest XLC compiler with xlclang++ front-end. On AIX, the XLC 16.1.0.1 compiler considers the call to `std::abs` ambigious, so it needs help with a static_cast to the type of the template argument.
