Alexey Bataev b99dcb5f31 [OPENMP, NVPTX] Do not globalize local variables in parallel regions. 
In generic data-sharing mode we are allowed to not globalize local
variables that escape their declaration context iff they are declared
inside of the parallel region. We can do this because L2 parallel
regions are executed sequentially and, thus, we do not need to put
shared local variables in the global memory.

Alexey Bataev 91433f6877 [OPENMP, NVPTX] Reduce the number of the globalized variables. 
Patch tries to make better analysis of the variables that should be
globalized. From now, instead of all parallel directives it will check
only distribute parallel .. directives and check only for
firstprivte/lastprivate variables if they must be globalized.
