    c++: fold calls to std::forward_like [PR96780]

    This extends our folding of cast-like standard library functions
    to also include C++23's std::forward_like.

            PR c++/96780

    gcc/cp/ChangeLog:

            * cp-gimplify.cc (cp_fold) <case CALL_EXPR>: Fold calls
            to std::forward_like as well.

    gcc/testsuite/ChangeLog:

            * g++.dg/opt/pr96780.C: Also test std::forward_like folding.
