Update poclbm kernel for better performance on GCN and new SDKs with bitalign support when not BFI INT patching.

If there are no GPUs, set nDevs to 0 not -1 (status is set to an

status value).
Also, if nDevs is -1, exit rather than screwing up later.

Use a buffer of up to 512 * 4 integers when retrieving work from the GPU.
This allows each local thread id to have one slot to put any positive results into, thus making overlapping results far less likely.
Thus races will be much rarer, allowing more threads.
It should also pick up blocks close to each other more reliably and hopefully decrease the number of rejects and opencl errors.
Do the search over the buffer entirely in a separate thread to allow the GPU to stay as busy as possible.
Detach threads from themselves to prevent unlucky even where dereferencing occurs by freeing the data that stores the thread info.
