Peter Boyle 66b529b345 sumD_gpu_reduce_words: fuse pack+reduce into single packReduceKernel ...

Replace the two-kernel pack+reduce sequence with a single fused kernel
packReduceKernel<R> that reads R words of each vobj at offset 'base'
and accumulates directly into iVector<iScalar<scalarD>,R>, eliminating
the intermediate bundle buffer entirely.

HBM access per word-group drops from 3x (pack-read + pack-write +
reduce-read) to 1x.  Thread count comes from getNumBlocksAndThreads
(warpSize..256) rather than acceleratorThreads(), so occupancy is
correct regardless of the --accelerator-threads setting.
