    ifcvt: rewrite args handling to remove lookups

    This refactors the code to remove the args cache and index lookups
    in favor of a single structure. It also again, removes the use of
    std::sort as previously requested but avoids the new asserts in
    trunk.

    gcc/ChangeLog:

            PR tree-optimization/109154
            * tree-if-conv.cc (INCLUDE_ALGORITHM): Remove.
