Intel's blending hardware does not properly return 1.0 for destination
alpha for RGBX formats; it requires the factors to be overridden to
either zero or one. Broadcom vc4 and v3d also could use this override.
While overriding these factors is safe in general, Nouveau and Radeon
would prefer not to. Their blending hardware already returns correct
values for RGB/RGBX formats, and would like to avoid the resulting
per-buffer blending and independent blend factors (rgb != a) since it
can cause additional overhead.
I considered simply handling this in the driver, but it's not as nice.
pipe_blend_state doesn't have any format information, so we'd need the
hardware blend state to depend on both pipe_blend_state and
pipe_framebuffer_state. Furthermore, Intel GPUs don't have a native
RGBX_SNORM format, so I avoid exposing one, which makes Gallium fall
back to RGBA_SNORM. The pipe_surfaces we get in the driver have an RGBA
format, making it impossible to tell that there shouldn't be an alpha
channel. One could argue that st not handling it in that case is a bug.
To work around this, we'd have to expose RGBX pipe formats, mapped to
RGBA hardware formats, and add format swizzling special cases. All
doable, but it ends up being more code than I'd like.
st_atom_blend already has access to the right information and it's
trivial to accomplish there, so we just add a cap bit and do that.

Gallium historically has treated pipeline statistics queries as a single
query, PIPE_QUERY_PIPELINE_STATISTICS, which returns a block of 11
values. This was originally patterned after the D3D1x API. Much later,
Brian introduced an OpenGL extension that exposed these counters - but
it exposes 11 separate queries, each of which returns a single value.
Today, st/mesa simply queries all 11 values, and returns a single value.
While pipeline statistics counters aren't typically performance
critical, this is still not a great fit. A D3D1x->GL translator might
request all 11 counters by creating 11 separate GL queries...which
Gallium would map to reads of all 11 values each time, resulting in a
total 121 counter reads. That's not ideal.
This patch adds a new cap, PIPE_CAP_QUERY_PIPELINE_STATISTICS_SINGLE,
and corresponding query type PIPE_QUERY_PIPELINE_STATISTICS_SINGLE.
When calling create_query(), q->index should be set to one of the
PIPE_STAT_QUERY_* enums to select a counter. Unlike the block query,
this returns the value in pipe_query_result::u64 (as it's a single
value) instead of the pipe_query_data_pipeline_statistics group.
We update st/mesa to expose ARB_pipeline_statistics_query if either
capability is set, preferring the new SINGLE variant when available.
Thanks to Roland, Ilia, and Marek for helping me sort this out.

This just changes the order of the switch statements, so we only
look at target if the query type is PIPE_QUERY_PIPELINE_STATISTICS.

Gallium handles pipeline statistics queries as a single query
(PIPE_QUERY_PIPELINE_STATISTICS) which returns a struct with 11 values.
Sometimes it's useful to refer to each of those values individually,
rather than as a group. To avoid hardcoding numbers, we define a new
enum for each value. Here, the name and enum value correspond to the
index in the struct pipe_query_data_pipeline_statistics result.

We get a payload for the ivec3 workgroup and an int local invocation
index, and we use the core lowering to turn into the global invocation id
and the local invocation id ivec3s.
This is only exposed on V3D 4.1+, because we didn't have the TMU write
operations for images on 3.3 (To do GLES 3.1 there, you have to lower it
to SSBO load/stores, which is a problem to solve later).
This was an arbitrary "we support lots of stuff" value when I started the
driver. However, at 400 we expose OES_gpu_shader5, which claims support
for dynamically indexing samplers, which the driver doesn't do yet.
We've been relying on linking splitting up our varying matrices into
separate vectors, but with SSO that doesn't happen. Supporting matrix
inputs isn't too hard, though.
Otherwise, the simulator raises the GMP interrupt and waits for it to be
handled, and v3d ends up spinning in v3d_hw_tick(). Aborting right when
violation happens gives us a chance to look at the backtrace of whatever
thread triggered the violation.

The original idea was that the backend compiler could eliminate
surfaces, so we would have it mark which ones are actually used,
then shrink the binding table accordingly. Unfortunately, it's a
pretty blunt mechanism - it can only prune things from the end,
not the middle - since we decide the layout before we even start
the backend compiler, and only limit the size. It also basically
gives up if it sees indirect array access.
Besides, we do the vast majority of our surface elimination in NIR
anyway, not the backend - and I don't see that trend changing any
time soon. Vulkan abandoned this plan a long time ago, and I don't
use it in Iris, but it's still been kicking around in i965.
I hacked shader-db to print the binding table size in bytes, and
observed no changes with this patch. So, this code appears to do
nothing useful.

Instead of emitting all of the conditions for the cases of a switch

case. The original justification for this was that we were going to
have to build a default case anyway which would need them all. However,
we can just trust CSE to clean up the mess in that case. Emitting each
condition right before the if statement that uses it reduces register
pressure and, in one customer benchmark, reduces spilling and improves
performance by about 2x.
