intel/blorp: Disable sampler state prefetching on Gen11

Sampler state prefetching is broken on Gen11, and WA_160668216 says
to disable it.  Apparently sampler state prefetching also has basically
zero impact on performance, so we don't need to worry there.

i965, anv, and iris already handle this correctly, but we missed BLORP.
Ideally the kernel should globally disable this by writing SARCHKMD, at
which point we wouldn't have to worry about it.  But let's be defensive
and handle it ourselves too.

iris: move sysvals to their own constant buffer

This commit moves the sysvals to a separate, new constant buffer
at the end (before the shader constants). It also allows us to
remove the special handling we had for cbuf0, and enables all
constant buffers to support user-specified resources and user
buffers.

v2: (by Kenneth Graunke)
- Rebase on the previous patch to fix system value uploading.
- Fix disk cache num_cbufs calculation
- Fix passthrough TCS to report num_cbufs = 1 so upload actually occurs
- Change upload_sysvals to assert that num_cbufs > 0 when
  num_system_values > 0.

panfrost: Implement command stream scoreboarding

This is a rather complex change, adding a lot of code but ideally
cleaning up quite a bit as we go.

Within a batch (single frame), there are multiple distinct Mali job
types: SET_VALUE, VERTEX, TILER, FRAGMENT for the few that we emit right
now (eventually more for compute and geometry shaders). Each hardware
job has a mali_job_descriptor_header, which contains three fields of
interest: job index, a dependencies list, and a next job pointer.

The next job pointer in each job is used to form a linked list of
submitted jobs. Easy enough.

The job index and dependencies list, however, are used to form a
dependency graph (a DAG, where each hardware job is a node and each
dependency is a directed edge). Internally, this sets up a scoreboarding
data structure for the hardware to dispatch jobs in parallel, enabling
(for example) vertex shaders from different draws to execute in parallel
while there are strict dependencies between tiling the geometry of a
draw and running that vertex shader.

For a while, we got by with an incredible series of total hacks,
manually coding indices, lists, and dependencies. That worked for a
moment, but combinatorial kaboom kicked in and it became an
unmaintainable mess of spaghetti code.

We can do better. This commit explicitly handles the scoreboarding by
providing high-level manipulation for jobs. Rather than a command like
"set dependency #2 to index 17", we can express quite naturally "add a
dependency from job T on job V". Instead of some open-coded logic to
copy a draw pointer into a delicate context array, we now have an
elegant exposed API to simple "queue a job of type XYZ".

The design is influenced by both our current requirements (standard ES2
draws and u_blitter) as well as the need for more complex scheduling in
the future. For instance, blits can be optimized to use only a tiler
job, without a vertex job first (since the screen-space vertices are
known ahead-of-time) -- causing tiler-only jobs. Likewise, when using
transform feedback with rasterizer discard enabled, vertex jobs are
created (to run vertex shaders) with no corresponding tiler job. Both of
these cases break the original model and could not be expressed with the
open-coded logic. More generally, this will make it easier to add
support for compute shaders, geometry shaders, and fused jobs (an
optimization available on Bifrost).

Incidentally, this moves quite a bit of state from the driver context to
the batch, which helps with Rohan's refactor to eventually permit
pipelining across framebuffers (one important outstanding optimization
for FBO-heavy workloads).

v2: Add comment explaining the meaning of "primary batch" as suggested
by Tomeu (trivial - not reviewed).
