The method `markWord::set_displaced_mark_helper` has no return statement at the end. So I want the `markWord::displaced_mark_helper` to be consistent with `markWord::set_displaced_mark_helper`.

I didn't notice the compiler warning, but the IDE `CLion` warns that the return statement is `unreachable code`.
