I added an end-to-end Flang → LLVM IR test for taskgroup task_reduction enclosing target in_reduction. This goes through %flang_fc1 -emit-llvm -fopenmp -fopenmp-version=50 and checks the full seam: __kmpc_taskred_init from the enclosing taskgroup, __kmpc_task_reduction_get_th_data(..., ptr null, ...) in the outlined target body, and the load/store through the returned private pointer.
