winsys/amdgpu: enlarge buffer_indices_hashlist
Enlarge the buffer hashlist to prevent large numbers of misses due to adding more buffers than can be cached in the hashlist. The game I tested had CS's with up to 1500 buffers and the overhead of amdgpu_lookup_buffer for various sizes was: 4096 1.97% (new value) 2048 4.37% 1024 6.92% 512 9.47% (old value) (percentage of CPU usage in render thread as determined by perf) The time spent in amdgpu_add_buffer self is ~4.2% in all cases and for 4096 the time needed to clear the hashlist is still < 0.10%, so I am not expecting significant regressions.
