706c9f2d60 iris: Skip double-disabling TCS/TES/GS after BLORP operations
BLORP always turns off TCS/TES/GS.  If regular drawing also has them
disabled (the overwhelmingly common case), then leaving them disabled
is just fine by us and we can skip dirtying them, as that would just
re-disable them a second time on the next draw.

If they are actually enabled, however, we do need to flag them.

a16975e615 iris: Rework iris_update_draw_parameters to be more efficient
This improves a couple of things:

1. We now only update anything if the shader actually cares.

   Previously, is_indexed_draw was causing us to flag dirty vertex
   buffers, elements, and SGVs every time the shader switched between
   indexed and non-indexed draws.  This is a very common situation,
   but we only need that information if the shader uses gl_BaseVertex.

   We were also flagging things when switching between indirect/direct
   draws as well, and now we only bother if it matters.

2. We upload new draw parameters only when necessary.

   When we detect that the draw parameters have changed, we upload a
   new copy, and use that.  Previously we were uploading it every time
   the vertex buffers were dirty (for possibly unrelated reasons) and
   the shader needed that info.  Tying these together also makes the
   code a bit easier to follow.

In Civilization VI's benchmark, this code was flagging dirty state
many times per frame (49 average, 16 median, 614 maximum).  Now it
occurs exactly once for the entire run.

896885025f util/u_queue: track job size and limit the size of queue growth
When both UTIL_QUEUE_INIT_RESIZE_IF_FULL and
UTIL_QUEUE_INIT_USE_MINIMUM_PRIORITY are set, we can get into a
situation where the queue never executes and grows to a huge size
due to all other threads being busy.

This is the case with the shader cache when attempting to compile a
huge number of shaders up front. If all threads are busy compiling
shaders the cache queues memory use can climb into the many GBs
very fast.

The use of these two flags with the shader cache is intended to
allow shaders compiled at runtime to be compiled as fast as possible.
To avoid huge memory use but still allow the queue to perform
optimally in the run time compilation case, we now add the ability
to track memory consumed by the jobs in the queue and limit it to
a hardcoded 256MB which should be more than enough.

3da8a8a3d6 iris: Avoid uploading SURFACE_STATE descriptors for UBOs if possible
If we can entirely push uniform data, we don't need a SURFACE_STATE
descriptor for pulling data.  Since constant uploads are a very common
operation, and being able to push all data is also very common, we would
like to avoid the overhead in this case.

This patch defers uploading new descriptors.  Instead of handling that
at iris_set_constant_buffer, we do it at iris_update_compiled_shaders,
where we can see the currently bound shader variants.  If any need pull
descriptors, and descriptors are missing, we update them and flag that
the binding table also needs to be refreshed.

dd83ef0d1a iris: Track per-stage bind history, reduce work accordingly
We now track per-stage bind history for constant and shader buffers,
shader images, and sampler views by adding an extra res->bind_stages

1e7daaa6c9 iris: Don't flag IRIS_DIRTY_BINDINGS for constant usage history
The underlying buffer isn't changing - so we don't need to update any
SURFACE_STATE descriptors - we just might have new constants, meaning
we need to re-emit 3DSTATE_CONSTANT_XS.  On Gen9, this means we need
to update 3DSTATE_BINDING_TABLE_POINTERS_XS too, but that's now handled
by the explicit check in the previous patch.

On Gen9, this should cause us to re-emit the binding table /pointer/ on
writing to a buffer with PIPE_BIND_CONSTANT_BUFFER, rather than emitting
a whole new /table/.

On Gen8 and Gen11, this avoids binding table churn altogether.

e7db3577f8 iris: Explicitly emit 3DSTATE_BTP_XS on Gen9 with DIRTY_CONSTANTS_XS
Right now, we usually flag both IRIS_DIRTY_{CONSTANTS,BINDINGS}_XS,
because we have SURFACE_STATE for constant buffers in case the shaders
access them via pull mode.

But this flagging is overkill in many cases.  Gen8 and Gen11 don't need
it at all.  Gen9 doesn't need that large of a hammer in all cases.

Just handle it explicitly so the right thing happens.
