        * params.def (PARAM_LOGICAL_OP_NON_SHORT_CIRCUIT): New param.
        * tree-ssa-ifcombine.c (ifcombine_ifandif): If
        --param logical-op-non-short-circuit is present, override
        LOGICAL_OP_NON_SHORT_CIRCUIT value from the param.
        * fold-const.c (fold_range_test, fold_truth_andor): Likewise.
