Not clean because [RISC-V intrinsics for divideUnsigned and remainderUnsigned were added in JDK22](https://github.com/openjdk/jdk/commit/40a3c35aa5614be4505013d4e92ddb1b556a3622); aarch64 intrinsics for divideUnsigned and remainderUnsigned confirmed to be [released in JDK20](https://bugs.openjdk.org/browse/JDK-8287926).

Although originally intended to fix the test failing for RISC-V intrinsics, without this exclusion the test will also fail for aarch64 platforms, thus it is included as part of the backport.
