This patch removes the addition of 1 to the number of iterations when calling the following DeviceRTL functions: - `__kmpc_distribute_for_static_loop*` - `__kmpc_distribute_static_loop*` - `__kmpc_for_static_loop*` Calls to these functions are currently only produced by the OMPIRBuilder from flang, which already passes the correct number of iterations to these functions. By adding 1 to the received `num_iters` variable, worksharing can produce incorrect results. This impacts flang OpenMP offloading of `do`, `distribute` and `distribute parallel do` constructs. Expecting the application to pass `tripcount - 1` as the argument seems unexpected as well, so rather than updating flang I think it makes more sense to update the runtime.
