This PR adds support seq_cst (sequential consistency) clause for the flush directive in OpenMP. The seq_cst clause enforces a stricter memory ordering, ensuring that all threads observe the memory effects of the flush in the same order, improving consistency in memory operations across threads. --------- Co-authored-by: Shashwathi N <nshashwa@pe28vega.hpc.amslabs.hpecorp.net> Co-authored-by: CHANDRA GHALE <chandra.nitdgp@gmail.com>
