Once the kernel address is known, cuda-gdb no longer breaks on the stub. If I set breakpoint after the kernel is known, it's set on the kernel only and never stops on stub.

According to our debugger developers, cuda-gdb's behavior is not upstreamable. I can limit this patch to HIP if it is not needed for CUDA.
