Alexey Bataev f2f39be9ed [OPENMP][NVPTX]Emit correct reduction code for teams/parallel
reductions.

Fixed previously committed code for the reduction support in
teams/parallel constructs taking into account new design of the NVPTX
support in the compiler. Teams reduction are not fully functional yet,
it is going to be fixed in the following patches.
