This patch adds semantics for the `omp fuse` directive in flang, as specified in OpenMP 6.0. This patch also enables semantic support for loop sequences which are needed for the fuse directive along with semantics for the `looprange` clause. These changes are only semantic. Relevant tests have been added , and previous behavior is retained with no changes. --------- Co-authored-by: Ferran Toda <ferran.todacasaban@bsc.es> Co-authored-by: Krzysztof Parzyszek <Krzysztof.Parzyszek@amd.com>
