Parallel region reporting.
* __kmp_itt_region_forking should be called by master thread of a team. Exact moment of
call does not matter, but it should be completed before any thread of this team calls
__kmp_itt_region_starting.
* __kmp_itt_region_starting should be called by each thread of a team just before entering
parallel region body.
* __kmp_itt_region_finished should be called by each thread of a team right after returning
from parallel region body.
* __kmp_itt_region_joined should be called by master thread of a team, after all threads
called __kmp_itt_region_finished.
Note: Thread waiting at join barrier (after __kmp_itt_region_finished) can execute some more
user code -- such a thread can execute tasks.
Note: The overhead of logging region_starting and region_finished in each thread is too large,
so these calls are not used.

Barriers reporting.
A barrier consists of two phases:
1. Gather -- master waits for arriving of all the worker threads; each worker thread
registers arrival and goes further.
2. Release -- each worker threads waits until master lets it go; master lets worker threads
go.
Function should be called by each thread:
* __kmp_itt_barrier_starting() -- before arriving to the gather phase.
* __kmp_itt_barrier_middle() -- between gather and release phases.
* __kmp_itt_barrier_finished() -- after release phase.
Note: Call __kmp_itt_barrier_object() before call to __kmp_itt_barrier_starting() and save
result in local variable. __kmp_itt_barrier_object(), being called too late (e. g. after gather
phase) would return itt sync object for the next barrier!
ITT need an address (void *) to be specified as a sync object. OpenMP RTL does not have
barrier object or barrier data structure. Barrier is just a counter in team and thread
structures. We could use an address of team structure as an barrier sync object, but ITT wants
different objects for different barriers (even whithin the same team). So let us use
team address as barrier sync object for the first barrier, then increase it by one for the next
barrier, and so on (but wrap it not to use addresses outside of team structure).
