        Description

        TestInterfaceMethodSelection has shown a bug in the template interpreter on s390. Restore functions for locals (R12 = Z_tmp_3) and bcp (R13 = Z_tmp_4) are used without having saved the correct values.
        In addition, C2 currently uses a constant size for partialSubtypeCheckNode which uses load_const_optimized with variable size.
