        * tree-core.h (enum operand_equal_flag): Add OEP_NO_HASH_CHECK.
        * fold-const.c (operand_equal_p): If flag_checking and
        OEP_NO_HASH_CHECK is not set in flag, recurse with OEP_NO_HASH_CHECK
        and if it returns non-zero, assert iterative_hash_expr on both
        args is the same.
