4604         The call to already_seen_tag introduces an O(N^2) when running
4605         gengtype on N, the number of tags, due to the repeated linear
4606         search, but currently max(N) is relatively small (the number of

4614         GIMPLE_OMP_RETURN happens to share the data layout of
4615         GIMPLE_OMP_ATOMIC_STORE, they are not otherwise related.
4616         (GIMPLE_OMP_PARALLEL, GIMPLE_OMP_TARGET): Likewise, rename
4617         underlying GSS value from GSS_OMP_PARALLEL to
4618         GSS_OMP_PARALLEL_LAYOUT to make clear that these gimple codes are

4620         (GIMPLE_OMP_SINGLE, GIMPLE_OMP_TEAMS): Likewise, rename GSS values
4621         for these two codes from GSS_OMP_SINGLE to GSS_OMP_SINGLE_LAYOUT.

4638         stmt->code == GIMPLE_EH_DISPATH.
4639
4640         (gimple_statement_omp_parallel): The existing class expressed
4641         a layout (GSS_OMP_PARALLEL), but the codes with that layout
4642         are not all related, so it makes more sense for this class to
4643         express a *code* (GIMPLE_OMP_PARALLEL).  GSS_OMP_PARALLEL has
4644         been renamed to GSS_OMP_PARALLEL_LAYOUT to express this, so

4651         as used by the various gimple_omp_taskreg_ accessors.
4652         (gimple_statement_omp_parallel): Reintroduce this class, this time
4653         as a subclass of gimple_statement_omp_taskreg to express the
4654         invariant stmt->code == GIMPLE_OMP_PARALLEL.
4655         (gimple_statement_omp_target) New class, subclassing
4656         gimple_statement_omp_parallel_layout, to express the invariant
4657         stmt->code == GIMPLE_OMP_TARGET.
4658         (gimple_statement_omp_task): Update to inherit from

4676         with code == GIMPLE_OMP_ATOMIC_STORE.
4677         (gimple_statement_omp_return): New class, subclassing
