freedreno/a4xx: better occlusion/sample counting
This seems to give more reliable results. More similar to what we do on
a3xx, although I think it breaks the a3xx theory that the four sets of
results map to each MRT (since we appear to still only have four sets on
a4xx). The divide-by-two is a bit odd, but seems to be needed for some
reason.
