The ocml functions are pointless wrappers around the intrinsics. I wouldn't be shocked if llvm.lrint/llrint were broken in some way, but llvm.rint directly maps to an instruction and should work. Even if the instruction were broken, the correct implementation is have the backend work around the instruction
