        comparison ops instead of result_type so result_type still holds type
        in which comparison is done.  When checking for comparison between

        type of op0.  Don't warn about equality comparison of signed operand
        to unsigned constant that fits in signed type.

        * fold-const.c (decode_field_reference): Don't check TREE_CODE
        of EXP; let get_inner_reference decide if have reference.
        Allow no bit reference if have AND_MASK.
        (all_ones_mask_p): Use tree_int_cst_equal, not operand_equal_p.
        (unextend): New function.
        (fold_truthop): For constant cases, use new function, rework
        conversion, and warn if comparison can never be true.

        * expr.c (store_expr): Do conversion in two steps for promoted lhs.
