[PATCH] D25343: [OpenCL] Mark group functions as noduplicate in opencl-c.h

clang does not recognize convergent as a valid attribute.  There was an attempt to add this, see https://www.mail-archive.com/cfe-commits@lists.llvm.org/msg22271.html but it hasn't had any result.  Matt do you see "real uses" for this now?
