RFR: JDK-8291735: methods_do() always run at exit

[Tobias Holenstein]

`SystemDictionary::methods_do` is always executed because we miss parenthesis around the first `or`. `&&` binds stronger than `||` and therefore the condition become true if `ProfileInterpreter` is true. 

Fixed by adding the missing parenthesis.
