SYCL / Linux / OCL x64 LLVM Test Suite failure is not related to the fix as the test doesn't contain any half types.
The rest of test failures are related to tests that used to fail in esimd emulator but passing now. It is addressed in test PR

The actual failing test is XPTI/kernel/content.cpp and the error is some test execution. It is not related to the fix since fix is specific to half type that is executed on emulator. This test does not contain any half type data so the failure is not related to the fix
