gallium/radeon: add query fences and r600_get_hw_query_params
We will support the waiting option in ARB_query_buffer_object using
WAIT_REG_MEM on an appropriate fence-like dword. Some queries
conveniently
write their results with the highest bit set, and we can just use
that;
for others, we have to write a fence explicitly.
ZPASS_DONE for occlusion queries writes its results with the high
bit
set, but it writes up to 8 pairs of results (one for each DB). We
have
to wait for all of these results, so let's just add an explicit
fence.
The new function provides summary information to be used by
subsequent
patches.
