The motivating factor is: this lowering may cause
nir_intrinsic_load_local_group_size intrinsics to be added to the
shader, and by moving this around we make possible for the drivers to
lower that intrinsic by themselves.
Iris will do just that in a later patch for implementing variable
group size.

(Co-authored with Chris Wilson.)
Frequently, games create fences and later check them with a timeout of
0 to see if that work has completed yet. They do not want the work to
be flushed immediately upon fence creation.
This is what PIPE_FLUSH_DEFERRED does - it inhibits the flush at fence
creation time, but still guarantees that a flush will occur later on
once fence_finish() is called.
Since syncpts can only occur at batch boundaries, when deferring a
flush, we have to wait for the syncpt at the end of the batch being
constructed. This is later than desired, but safe if blocking. To
avoid extra delays, we additionally insert a PIPE_CONTROL to write an
availability bit at the exact point of the fence. We can poll this
on the CPU, allowing us to check whether the fence has gone by, even
if the batch hasn't completed. It can also let us skip kernel calls.
Improves performance in Bioshock Infinite by 10% on Icelake GT2 on
-ForceCompatLevel=5 settings. Thanks to Felix Degrood and Mark Janes
for helping notice the extraneous stalls and batches, Marek Olšák for
adding deferred flush support to Gallium to solve this issue, and
Chris Wilson for reworking a lot of the internals of this work.

Receiving a fence_server_sync (iris_fence_await) means that any future
work needs to wait for the fence. But previous work doesn't need to.
So flush it now, to avoid delaying it arbitrarily.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3802>
In the next patch, we will introduce deferred fences where we will need
to flush a fence later. To do this, we need to know which batch requires
flushing, so keep a 1:1 mapping between seqno[] and the associated
batch.
It's also substantially less confusing to have a 1:1 mapping.

By using the breadcrumbs we inject into the batch, we can build a
lightweight fence - that can be evaluated in userspace without having to
check in the kernel. In order to pass the fences between processes, and
to wait efficiently, we continue to track the syncobj for each batch and
use that as a terminator for the fence, and for passing coarse
scheduling decisions to the kernel on execbuf.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3802>
We can use seqno as a basic for fast userspace fences: where we can
check a value directly to test for fence completion without having to
query using the kernel. To do so we need to write a breadcrumb from the
batch and track those writes as the basis for our lightweight fences.

Batches are going to have an uploader in the next commit, so destroying
batches will destroy uploaders, which will unmap transfers, which will
return things to the slab allocator. So we need to reorder destroying
the slab allocator to the end to avoid crashing.

We're going to need it to create a uploader in the batch soon. We still
avoid storing it, to maintain the charade of separation, and make people

things even worse.

Lets us drop some cut and pasted kernel header contents.
Linux 4.7 came out 4 years before we the first officially supported
release of this driver; iris won't run on kernels older than 4.16,
and 4.18.11+ is strongly recommended. So I suspect it's safe to
assume that a kernel header from 4.7 will exist at build time.

Now that we normalize our keys fairly well, build a variant at shader

We can remove a bunch of conditional code at key comparison time by
computing a bitmask of used key bits at ir3_shader creation time. This
also gives us a nice place to put additional key simplification to reduce
how many variants we create (like skipping rastflat if we don't read
colors in the FS, or skipping vclamp_color if we don't write colors).
It does mean walking the whole key to AND it, but the key is just 28 bytes
so far so that seems pretty fine.

We weren't filling in the tess mode of the key, or setting has_gs on GS
shaders, resulting in assertion failures when NIR intrinsics didn't get
lowered.
We have to make a guess at prim mode for TCS, but it should be better to
have some shader-db coverage than none, and it will avoid these failures
happening when we start precompiling shaders.
