AccessControlEnumerable.grantRole(bytes32,address) (#1517-1520) ignores return value by _roleMembers[role].add(account) (#1519)
AccessControlEnumerable.revokeRole(bytes32,address) (#1525-1528) ignores return value by _roleMembers[role].remove(account) (#1527)
AccessControlEnumerable.renounceRole(bytes32,address) (#1533-1536) ignores return value by _roleMembers[role].remove(account) (#1535)
AccessControlEnumerable._setupRole(bytes32,address) (#1541-1544) ignores return value by _roleMembers[role].add(account) (#1543)
Ensure that all the return values of the function calls are used.

BitrueToken.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#1625-1656) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (#1635)
Avoid relying on block.timestamp.
