r600g/compute: Add a function for defragmenting the pool

Browse source 
This new function will move items forward in the pool, so that
there's no gap between them, effectively defragmenting the pool.

For now this function is a bit dumb as it just moves items
forward without trying to see if other items in the pool could
fit in the gaps.
