The test checks x86 target in fsycl-is-device mode. x86 is not a valid offloading target and IMO test meant to check fsycl-is-host mode to make sure host invocations of __builtin_sycl_unique_stable_name work correctly. This also switches the test to use sycl_entry_point attribute instead of sycl_kernel because the intention for the future SYCL changes is to use sycl_entry_point and eventually remove sycl_kernel attribute when sycl_entry_point supports enough SYCL cases.
