    libstdc++: re-bump the feature-test macro for P2562R1 [PR119488]
    
    Now that the algorithms have been merged we can advertise full support
    for P2562R1. This effectively reverts r15-8933-ga264c270fde292.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/119488
            * include/bits/version.def (constexpr_algorithms): Bump
            the feature-testing macro.
            * include/bits/version.h: Regenerate.
            * testsuite/25_algorithms/cpp_lib_constexpr.cc: Test the
            bumped value for the feature-testing macro.
