there is no need to delay any further instructions that consume an

It seems for short frag shaders, too much prefetch can be detrimental.
I think what we *really* want to do is decide after pre-RA sched, when
we also know about nop's and what the actual ir3 instruction count is.
But that will require re-working how prefetch lowering works. For now
this is a super crude heuristic to attempt to approximate a good
solution.

We can no longer assume that `state->ranges[0]` is block 0. It *often*
is, but when we encounter a "real" ubo that we lower to `load_uniform`
before a block 0 `load_ubo`, it could end up another entry in the table.
Resulting in the second pass after gathering ubo ranges, not finding a
valid range. Which results in a `load_ubo` for a thing that is not
actually a ubo making it's way into ir3 frontend. Resulting in grabbing
what we think is a ubo address out of some unrelated const register, and
trying to dereference that. Which as you can imagine, fails in amusing
ways.

Corresponds roughly to what we analyze. Note that "terminate AND
execute" is a contradiction (rather: it's equivalent to just
terminating), hence why there are only three possibilities for the
states of the flags:
.cont = continue, don't execute
.last = don't continue, don't execute
.cont.last = continue and execute

This commit fixes a GS regression introduced in !4562 where
ir3's GS lowering pass was moved from common code (ir3_nir) to
freedreno-specific code (ir3_shader). For GS support in turnip, we
need to add the GS lowering pass back in, this time in tu_shader.
As for the nir_gather_info change, the GS lowering pass has always
introduced a discard_if intrinsic into the GS. Previously, we simply
ran nir_shader_gather_info before GS lowering, but now since we lower
the GS before we need to remove the assertion that only a FS can use
the discard_if intrinsic.

There is an annoying spec corner on Android. Because VkSwapchain is
implemented in the Vulkan loader on Android which may not know about
this extension, we have to handle it as a special case inside the
driver. We only have to do this on Android and only for VkSwapchainKHR.

The nir_analyze_ubo_ranges pass removes all UBO block 0 loads to reverse
what nir_lower_uniforms_to_ubo() had done, and we only upload UBO pointers
to the HW for UBO block 1-N, so let's just fix up the shader state.
Fixes an off by one in const state layout setup, and some really dodgy
register addressing trying to deal with dynamic UBO indices when the UBO
pointers happen to be at the start of the constbuf.
There's no fixes tag, though this fixes a bug from September, because it
would require the num_ubos fix in nir_lower_uniforms_to_ubo.

The fixed commit was really nice in mostly fixing num_ubos to reflect the
shader after lowering, but for
dEQP-GLES31.functional.compute.basic.ubo_to_ssbo_single_invocation there
are no default uniforms and so we skipped the increment, even though we
shifted the block index up.

Using non-write flags is pretty dubious -- it means the kernel tracking an
array of read-only consumers of the BO and having exclusive consumers wait
on each reader's fence. It allows multiple readers through dma-bufs to do
work in parallel, but at the cost of kernel CPU time and memory management
of the shared array. Other drivers have dropped this distinction since
dma-buf sharing is usually producer-consumer, not producer-two-consumers,
and the userspace and kernel space tracking is expensive.
For us, this lets us drop the flags passed in for relocs and tracked in
the ringbuffer reloc lists. The end result of the flags reduction work is

It's silly to have all the reloc emitters passing around FD_RELOC_READ
when you have to have it set on all relocs (that don't include WRITE,
which implies read) for the kernel to actually track the fences on the BO.

TMUSLOD register is the same that TMUS but having the same effect that
setting disable_autolod on the TMU configuration parameter 2.
So using that register is potentially more efficient, as in several
cases we would be able to skip writing P2.
One case where we can't use it is for texture cube maps, as we need to
use TMUSCM.

Texture access has three configuration parameters, P0 (texture), P1
(sampler) and P2(lookup). P1 and P2 are optional, but if P2 is needed
(like for example to set the offset for texelFetchOffset), then you
need to set P1.
But until now when setting up P1 we were asking the driver to fill up
the address with the shader state. But in that case we can just fill
that address with the default value NULL.
So let's avoid asking the driver to fill that default values, and do
it directly on the compiler. This is a good-to-have on OpenGL, and
likely would be needed on Vulkan.
