[PATCH] D30135: [OpenMP] Generate better diagnostics for cancel and cancellation point

I see. I think it is better to check the `CancelRegion` just before call of `CheckNestingOfRegions()` function. You need to extract checks for `CancelRegion` from `ActOnOpenMPCancellationPointDirective()` and `ActOnOpenMPCancelDirective()` functions into a standalone function and call it before `CheckNestingOfRegions()`.
