The new tests added in https://github.com/llvm/llvm-project/pull/169623 are [failing](https://lab.llvm.org/buildbot/#/builders/225/builds/544) on the Intel GPU runner, so XFAIL them as with the other tests. Signed-off-by: Sarnie, Nick <nick.sarnie@intel.com>
PR #144635 enabled non-contiguous updates for both `update from` and `update to` clauses, but tests for `update to` were missing. This PR adds those missing tests to ensure coverage.
