The nir approximation is a bit more precise so there is one more
instruction for the scalar version but if the shader actually uses
vector one or some other stuff like sin(x) followed by cos(x) we
save more.
This nir approximation importantly seems to have better precision
so this should also fix some piglits/dEQPs.

Looks like 3 implementations already have that field in their private
command_buffer struct, and having it at the vk_command_buffer opens the
door for generic (but suboptimal) secondary command buffer support.

Now that we have no overlapping memory addresses for different
contexts we can go ahead and also share the same VM for every context.
This should make VM binding much easier to implement once we have
Kernel support for it.
v2: We now have engines_ctx, set it there too.
v3: Fix indenting (Ken).

Have a single border color pool per bufmgr instead of per context.
We want to have a single VM shared among every context and the border
color pool is the last feature preventing us from having that.
Previously we had 1024 colors per context but once the buffer was full
we just waited for the buffer to be unused and restarted it. After
this patch we have 4096 colors for every single context and we can't
just flush buffers if they are full, so we simply return black.
There are many strategies we could try to implement to help alleviate
this new 4096 limit, none of which are implemented by this patch:
- We could just expand the buffer to the full 16MB we can use,
allowing 262144 colors.
- We could use multiple buffers and make the contexts refcount them,
so eventually older buffers would reach zero references and be
recycled, moving us to a working set maximum from a lifetime
maximum.
- We could also make the border color pool be a standard memzone and
then give smaller buffers to each context when they need, so the
limit would be in the number of contexts that can use border color
pools. This was my first implementation but Ken suggested I switch
to the one provided by this patch, which is simpler.
Keep it like this since border colors don't seem to be used very much
and other Mesa drivers such as radeonsi also seem to employ the
"return black once we reach the limit" strategy.
As a last note, we could also move the contents of iris_border_color.c
to iris_bufmgr.c in order to avoid breaking some abstractions we have
in Iris, like we do with iris_bufmgr_get_border_color_pool(). I can do
this in case we want it.
v2: Switch from standard memzone to a per-screen thing (see above).
v3: Actually make it per bufmgr. Just making it per screen is not
enough, since screens can share the same VM, an example being the
gputest benchmark suite.
v4: Rebase.
v5: Remove dead code, lock around hash table lookup (Ken).
v6: Simple rebase.
v7: Another rebase (for_each_batch).

We're moving towards a path where all contexts share the same virtual
memory - because this will make implementing vm_bind much easier - ,
and to achieve that we need to rework the binder memzone. As it is,
different contexts will choose overlapping addresses. So in this patch
we adjust the Binder to be 1GB - per Ken's suggestion - and use a real
vma_heap for it. As a bonus the code gets simpler since it just reuses
the same pattern we already have for the other memzones.

There's already a single command queue for the screen, meaning that
all commands are being serialized implicitly into that queue. There's
no need to have separate fences for parallel contexts when those
fences would all share the same underlying timeline.
This adds an explicit lock to expand the scope of the implicit screen
command queue ordering to include fence signals.
Each context still gets its own submit sequence, which is used for 1
purpose right now: A uniqueness check in the state manager to see
if states are coming from separate command lists, to apply promotion
and decay logic.

The no-wait condition was wrong before. If the query was used in the
current batch (query->fence_value == context->fence_value), we'd
continue on with the operation instead of returning false. Then the
buffer map would see that the bo is referenced in the current batch,
and would flush and wait, even though we were asked not to wait.
This fixes the condition by simply using the (correct) buffer map
logic.

Although a resource may support CCS with its original format, a texture
view of that resource may have a format that doesn't support
compression. Don't create CCS surface states for such texture views.

Fast clear with the resource format instead. This is safe to do because
can_fast_clear_color ensures that the clear color generates the same
pixel with either the view format or the resource format.
On SKL, this prevents us from using an invalid surface state. This platform
doesn't support CCS_E with sRGB formats, but prior to this patch we allowed
fast-clearing with this combination. Piglit's fcc-write-after-clear test
can trigger this.
