        * dojump.c (do_compare_and_jump): Canonicalize function pointers
        when one operand is a function pointer.  Use POINTER_TYPE_P and
        FUNC_OR_METHOD_TYPE_P.
        * expr.c (do_store_flag): Use POINTER_TYPE_P and FUNC_OR_METHOD_TYPE_P.
        * fold-const.c (build_range_check): Likewise.
        * match.pd (simple_comparison): Likewise.
