ABataev added a parent revision: D79186: [OPENMP]Consider 'omp_null_allocator' as a predefined allocator..

Predefined allocators should not be mapped at all (they are just enumeric
constants). FOr user-defined allocators need to map the traits only as
firstprivates, the allocator itself is private.
At the beginning of the target region the user-defined allocatores must
be created and then destroyed at the end of the target region:

  omp_allocator_handle_t my_allocator = __kmpc_init_allocator(<gtid>,
  /*default memhandle*/ 0, <number_of_traits>, &<traits>);
  ...
  call void @__kmpc_destroy_allocator(<gtid>, my_allocator);
