We were overflowing an array during bifrost disassembly. This was
only a problem if the user explicitly set an environment variable,
so unlikely to occur in casual use, and also only could be triggered
in very specific, dense code. But we still should get this right!
The specific CTS test that caused the assert is:
'dEQP-VK.graphicsfuzz.stable-quicksort-for-loop-with-injection'
with environment variable `BIFROST_MESA_DEBUG=shaders`. One of the
shaders has a clause with 6 constants (the maximum) and this overflowed
the array because we assume we always have an extra slot (used for
modifier processing).

Skip TU_CMD_FLAG_WAIT_FOR_BR wait whenever concurrent binning is disabled.
Without CB there is nothing to wait for, so the sync only adds overhead,
and in workloads with thousands of tiny renderpasses the cumulative overhead
becomes too big.
In one real-world workload I saw the following timings:
- 99.20 ms without disabling TU_CMD_FLAG_WAIT_FOR_BR
- 65.15 ms with TU_CMD_FLAG_WAIT_FOR_BR disabled
- 64.92 ms with TU_DEBUG=nocb

Disable concurrent binning by default so regular renderpasses have access
to all vertex fetch resources. When a renderpass can actually enable CB,
walk back to the CB barrier at submission time and re-enable CB for all
patchpoints between CB barrier and the renderpass.
Because we expect at most one or two renderpasses with CB per frame,
the number of patches stays small.
The reduced vertex fetch resources resulted in up to 10% performance loss
seen in targeted benchmark and in a few game captures.

The sync emitted on TU_CMD_FLAG_WAIT_FOR_BR didn't disable CB
when CB was previously disabled for the renderpass, this resulted
in less resources vertex processing resources available for BR.
We can just not emit the sync instead, since next time CB is enabled
it will force the sync.

While OpenGL 3.1 does require texture buffer objects, the ARB spec for
this requires support for texture buffers with alpha, luminance,
luminance-alpha and intensity formats in addition to RGBA formats. The
version of texture buffer objects that ended up in the OpenGL spec (even
in the compatibility spec) does not require these formats.
But, we don't even need to check this, because this is already included
in the GLSL 1.40 requirement that's also checked. So this shouldn't make
us expose GL 3.1 in cases where it isn't supported in the first place.

There's a single underlying bo mapping shared by the initial alloc here
and the later import of the same. The mapping size has to be initialized
with the real size of the created blob resource, since the app can query
the exported native handle size for re-import. e.g. lseek dma-buf size
Similar to virtgpu_bo_create_from_device_memory, the app can do multiple
imports with different sizes for suballocation. So on the initial
import, the mapping size has to be initialized with the real size of the
backing blob resource.

If the allocation originates from the same instance, the tracker map
size follows the allocationSize. After export and re-import, mapping the

Found when running glxgears with vblank enabled and modesetting DDX.
glxgears will send many present requests at the beginning, but most
of them get complete event with skip mode. This problem causes
glxgears report ~75fps on a 60Hz monitor at the first record.
This change reduces it to 60fps.
Vulkan side X11 WSI does not have this problem as it will wait first
present request's complete event before send second present request.
How the problem happens:
1. client send present request 1 with target msc = 1
2. server side current msc is 100, so it find request 1 is
outdated and queue it for vblank with target msc = 101
3. client send present request 2 with target msc = 2
4. server side current msc is still 100, so it find request 2
is outdated and queue it with target msc = 101, and find
request 1 will be overridden, so mark it as skipped and
send idle notify for it.
5. client get the idle notify for request 1, and reuse the
request 1 buffer for new back buffer to send present
request 3.
6. this keeps going until client send present request N, and
server finally process the vblank queue before 101 msc
arrive and send complete event for all these requests back
to client.

Rewrite ANV's encode.comp, the final intel-specific raytracing shader
used for bvh-build. Performance is greatly improved for this shader
by adding the following features:
1) Find children early. All threads speculative find their children
before they know if they are valid (not collapsed). This makes more
work overall but reduces latency for propagating valid nodes from
root to leaves. Nodes find out if they are valid faster if all nodes
know who their children are upfront.
2) Hoist code used for intra-thread communication. Communicate
to children as soon as possible, minimizing wait time for later
threads.
3) Multithread encoding. Still launching 1 simd lane per node, same
as before, but encoding of nodes and children are parallelized across
multiple lanes. This works well because most nodes are collapsed
without any encode work required.
4) Hash globalID. Reduce chance that the thread processing a node
will also need to process node's children, which was found to
degrade performance, particularly for root node processing.
