The GOMP_distribute_static_worksharing_dispatch and GOMP_loop_static_worksharing_dispatch builtins no longer pass loop bounds to OMPT. Instead, they pass the starting chunk and iteration count, which is the minimal information OMPT requires. This change simplifies the internal implementation and the external interface for OpenMP task offloading events.
