These optimizations are based on the fact that

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).

If we are about to write to a transform feedback buffer, we should

iris: Use stream uploader for shader draw parameters.

Most vertex data lives in user VBOs in IRIS_MEMZONE_OTHER, which
typically have high bits set to 0xffff.  The shader draw parameters were
being uploaded in IRIS_MEMZONE_DYNAMIC, which have high bets set to 0x2.
This was causing a lot of ping-ponging of high bits, leading to
unnecessary VF cache flushing.

Cuts 7.2% of the flushes in the Civizilation VI demo on Kabylake GT2.

iris: Don't check VF address high bits when there is no buffer.

If there is no buffer, then it doesn't matter.  Leave the old stale
high bits in place (for next time) and don't bother invalidating.

Cuts 5.6% of the flushes in the Civilization VI demo on Kabylake GT2.

iris: Drop RT flushes from depth stencil clearing flushes.

These write depth and stencil, not color writes, so there's no need
to flush the render target.

iris: Don't bother with PIPE_CONTROLs for CPU writes and no history

If a buffer has no usage history, we don't have any read only cache
invalidates to do.  If we've written it with the CPU, we don't need
to flush the render cache.  The only bit remaining is the CS stall
from iris_flush_bits_for_history.  We can just skip the PIPE_CONTROL
in this case.

This is pretty common - an app creates a buffer, fills it with data,
and then binds it for some purpose.

Cuts 36% of the flushes in Manhattan 3.0 on Kabylake GT2.

iris: Only do an RT flush for transfer maps if using copy_region.

If we wrote the data via the CPU, there's no point in doing a render
target flush.  If using BLORP, we do want a render target flush so the
data lands.

iris: Use iris_flush_bits_for_history in iris_transfer_flush_region

Instead of using the combined iris_flush_and_dirty_for_history, use
iris_flush_bits_for_history directly - we were already using the split
out iris_dirty_for_history.  There's no need to dirty twice, and we can
avoid the looping altogether for non-buffers.

iris: Avoid double flushing in iris_transfer_flush_region when copying.

My intention was to have iris_copy_region not do flushing, and leave
that up to the callers.  iris_resource_copy_region needs to do this,
but iris_transfer_flush_region was already doing it.  The net result
was that we were doing it twice for transfers.

So, move the flushing from iris_copy_region to iris_resource_copy_region
so that it only happens in the callers as I intended.

iris: Fix iris_flush_and_dirty_history to actually dirty history.

When I split iris_flush_and_dirty_history into two helper functions,
I accidentally made it stop dirtying.  Which was...sort of the point.

Fixes: 21688a306b2 iris: Split iris_flush_and_dirty_for_history into two helpers.

iris: Add maybe_flush calls to texture_barrier and memory_barrier

Otherwise, tests which loop on glMemoryBarrier may run us out of
batch space with piles of flushing.  (Ideally, we'd elide those bonus
PIPE_CONTROLs, but presumably this isn't that common of a case...)

Piglit's arb_pipeline_statistics_query-comp would hit this case after
some of the next patches remove other PIPE_CONTROLs with maybe_flushes.

iris: Implement INTEL_DEBUG=pc for pipe control logging.

This prints a log of every PIPE_CONTROL flush we emit, noting which bits
were set, and also the reason for the flush.  That way we can see which
are caused by hardware workarounds, render-to-texture, buffer updates,
and so on.  It should make it easier to determine whether we're doing
too many flushes and why.

panfrost: Skip shading unaffected tiles

Looking at the scissor, we can discard some tiles. We specifially don't
care about the scissor on the wallpaper, since that's a no-op if the
entire tile is culled.
