Subject: [PATCH 1/3] [NFC][clang] Fix
 CodeGenSYCL::unique_stable_name_windows_diff test

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.
