OMPT requires distinguishing these in its sync-region\ncallbacks.\n\nCreate new, semantically equivalent functions GOMP_barrier_ext and\nGOMP_barrier_cancel_ext with an integer `kind\u0027 parameter. Update all compiler\ncall sites to pass the appropriate constant. Preserve now unused functions\nGOMP_barrier and GOMP_barrier_cancel for backward compatibility.\n\nThe `kind\u0027 parameter is accepted but not yet acted upon in libgomp; it\nis reserved for future OMPT instrumentation.\n\ngcc/c-family/ChangeLog:\n\n\t* c-omp.cc (c_finish_omp_barrier): Pass GOMP_BARRIER_EXPLICIT to\n\tGOMP_barrier_ext.\n\ngcc/cp/ChangeLog:\n\n\t* semantics.cc
