Retest this please.

Looks like the the test fails when using `std` functions: ``` 4: [ RUN ] hip.mathspecialfunc_cbesselj2y2 4: /var/jenkins/workspace/Kokkos/core/unit_test/TestMathematicalSpecialFunctions.hpp:2132: Failure 4: Expected: (Kokkos::abs(h_cbj2(i) - h_ref_cbj2(i)))

I don't have much to add. You could try explicitly copying the kernel by swapping all `defined(KOKKOS_ARCH_INTEL_GPU)` with `0` in https://github.com/kokkos/kokkos/blob/5ad609661e570ba6aa7716a26a91cb67d559f8a2/core/src/SYCL/Kokkos_SYCL_Instance.hpp#L246-L354.

Looks like the `HPX` backend doesn't work with the changes here.
