I think NVIDIA NSight has some support for OpenCL debugging. AMD has another tool called CodeXL which provides debugging and profiling of OpenCL programs.
Currently I mostly use debug printfs and code reviews to do debug. Although I did run some OpenCL code under valgrind once to figure out a pointer handling issue. That was with AMD APP SDK running on the CPU side. If you run the code on the CPU even regular GDB should work, you might not get proper breakpoint settings etc thought since the code is in OpenCL rather than C/C++.
