        * expr.c (expand_expr_real_1): Just use do_store_flag.
        (do_store_flag): Drop support for TRUTH_NOT_EXPR.  Use
        emit_store_flag_force.
        * expmed.c (emit_store_flag_force): Copy here trick
        previously in expand_expr_real_1.  Try reversing the comparison.
        (emit_store_flag_1): Work if target is NULL.
        (emit_store_flag): Work if target is NULL, using the result mode
        from the comparison.  Use split_comparison, restructure final part
        to simplify conditionals.
