Some time ago I opened the following revision to fix an issue related to the implicit taskgroup associated with a taskloop construct that doesn't have the `nogroup` clause:


Those changes were upstreamed, but I forgot to update the documentation. This revision tries to address that.

In clang we explicitly materialize the implicit taskgroup when it is required. Thus, we always pass a `1` as the value of the nogroup parameter. Since this parameter doesn't represent whether the `nogroup` clause was present but whether we want to create a taskgroup region inside the kmpc_taskloop function, I think we should change its description.
