List::Util::XS - Indicate if List::Util was compiled with a C compiler

"List::Util::XS" can be used as a dependency to ensure List::Util was installed using a C compiler and that the XS version is installed. During installation $List::Util::XS::VERSION will be set to "undef" if the XS was not compiled. Starting with release 1.23_03, Scalar-List-Util is always using the XS implementation, but for backwards compatibility, we still ship the "List::Util::XS" module which just loads "List::Util".
