compute-runtime: XE_HP* related unit tests fail with all compute-runtime versions

Hi,

while trying to update the Debian packages for the Intel OpenCL stack, I’ve run into two failing tests:

./opencl/test/unit_test/kernel/cache_flush_xehp_and_later_tests.inl:345: Failure
Expected equality of these values:

    Which is: { 8-byte object <01-E0 5D-F0 AD-55 00-00>, 8-byte object <01-00 5E-F0 AD-55 00-00>, 8-byte object <00-20 5E-F0 AD-55 00-00> }

This happened while building intel-compute-runtime 22.03.22192 using igc 1.0.9933 and llvm-12. There may well be some unsupported combination of build dependency versions … I’m thankful for any pointer where to start looking. (I can successfully build 21.32.20609 using igc 1.0.8744 (or 1.0.9933 as well) and llvm-12 in the same setup. I haven’t tried any versions inbetween.)
