Failing tests are unrelated

That is not enough, we need at the very least to list the failures here so that they can be found later to gather statistics and help in analysis of flaky failures.

@dm-vodopyanov , please don't merge the PRs with failing tests without that done (or GH issues created).

Failures, HIP:

Failed Tests (2):
  SYCL :: Basic/parallel_for_user_types.cpp
