8319970: AArch64: enable tests compiler/intrinsics/Test(Long|Integer)UnsignedDivMod.java on aarch64

[cost0much]

Backport of JDK-8319970 that enables tests for compiler/intrinsics/Test(Long|Integer)UnsignedDivMod.java on aarch64. Not clean because RISC-V intrinsics for divideUnsigned and remainderUnsigned were added in JDK22; aarch64 intrinsics for divideUnsigned and remainderUnsigned confirmed to be released in JDK20.

This includes backport of JDK-8319960 because the UDivModI or UDivModL nodes are supplied from x86_64.ad, thus these node checks are intended for x64 platforms. 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.

Passes affected tests on Linux aarch64 and Mac aarch64.

⚠️ @cost0much This change is now ready for you to apply for maintainer approval. This can be done directly in each associated issue or by using the /approval command.

[cost0much]

/approval 8319970 request Improves coverage for aarch64 platforms for compiler/intrinsics/Test(Long|Integer)UnsignedDivMod. Does not apply cleanly due to RISC-V intrinsics support only in later versions. Affected tests pass. Risk is low: the change is test code only.

/approval 8319960 request Fixes compiler/intrinsics/Test(Long|Integer)UnsignedDivMod failing when enabled for non-x64 platforms. Applies cleanly and affected tests pass. Risk is low: the change is test code only.
