This PR adds several new tests for mapping of chained structures, i.e. those resembling: #pragma omp target map(tofrom: a->b->c) These are currently XFAILed, although the first two tests actually work with unified memory -- I'm not sure if it's possible to easily improve the condition on the XFAILs in question to make them more accurate. These cases are all fixed by the WIP PR https://github.com/llvm/llvm-project/pull/153683.
