s390: [cleanup] Avoid {Object::operator->}

Port 878ccb33

Original Commit Message:

    This CL was generated by an automatic clang AST rewriter using this
    matcher expression:

      callExpr(
        callee(
          cxxMethodDecl(
            hasName("operator->"),
            ofClass(isSameOrDerivedFrom("v8::internal::Object"))
          )
        ),
        argumentCountIs(1)
      )

    The "->" at the expression location was then rewritten to ".".
