[Beignet] opencl-1.2 branch head compile error and warnings

[Robert Jobbagy]

Hi,

After the update I gave this error :

/beignet_opencl_1_2/backend/src/ocl_barrier.ll:9:50: error: expected
top-level entity
declare void @__gen_ocl_barrier_local() nounwind noduplicate alwaysinline
                                                 ^
make[2]: *** [backend/src/ocl_barrier.ll.bc] Error 1
make[1]: *** [backend/src/CMakeFiles/beignet.bc.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

I used llvm 3.3-5ubuntu4

workaround:
I removed all noduplicate marker from declares and defines

I saw these warnings too:

I made something wrong ? Previous version (2013-12-05) compiled fine.
