[PATCH] ittnotify fixes

[Jonathan Peyton]

Hi hfinkel,

Added time-taking into hierarchical barrier (to fix CQ562639).
Added the check of the nested level to all notifications, restructure all checks to be consistent.
Disabled notifications from the teams construct (because all the parallel regions in the teams are nested from library POV).
