GCC now introduces OMPT-compatible variants for GOMP_scope_start and GOMP_scope_end. When the -fopenmp-ompt flag is enabled, these new builtins are used for task reductions, providing better instrumentation capabilities for tools. Previously, GOMP_scope_start was emitted only for task reductions without OMPT.
