openmp: Handle explicit linear clause properly in combined constructs with target [PR99928]
linear clause should have the effect of firstprivate+lastprivate (or for IVs
not declared in the construct lastprivate) on outer constructs and eventually
map(tofrom:) on target when combined with it.

PR middle-end/99928
* gimplify.c (gimplify_scan_omp_clauses) <case OMP_CLAUSE_LINEAR>: For
explicit linear clause when combined with target, make it map(tofrom:)
instead of no clause or firstprivate.
* c-c++-common/gomp/pr99928-4.c: Remove all xfails.
* c-c++-common/gomp/pr99928-5.c: Likewise.
