041451b655 agx/tilebuffer: Support layered layouts
Just add a flag for it. We don't care about the actual # of layers when
calculating the layout, only the boolean fact of being layered or not. The
reason we need this at all is because the eMRT implementation needs to
account for layering and that is only keyed off the tilebuffer layout.

73fb1543fd asahi: Do not support masking with spilled RTs
Extra complexity for this interaction, not worth it until we have an actual use
case IMHO.

6bc42054d1 asahi: Introduce concept of spilled render targets
To accommodate framebuffers which exceed tilebuffer limits, we'll need to spill
render targets to main memory. In effect, we need to emulate an immediate-mode
renderer for some render targets. This decision is made on a per-render target
basis. In our tilebuffer layout calculation, rather than asserting that all
render targets fit, introduce a notion of spilling.

This doesn't actually implement spilling -- it just pushes the assert failure
down to the users. But it's progress.

7b1d6204c8 asahi: Use nonempty tib for MSAA
Affects
dEQP-GLES31.functional.texture.multisample.samples_4.use_texture_depth_2d. This
needs tests, but whatever, 70% of the YouTube chat said to land the hack.

1dd872ec17 asahi: Assert on TIB strides > 64
These just don't seem to work. macOS falls back to eMRT here...

dEQP-GLES3.functional.draw_buffers_indexed.random.max_implementation_draw_buffers.13
from Fail -> Crash. Proper solution will come when we implement eMRT later on.

029c686c6d asahi: Implement color masks with masked stores
Blend states can require masking colour. Currently, this is handled by
nir_lower_blend, which lowers masks to a read-modify-write operation as required
on Mali hardware. However, our "tilebuffer store" instruction supports a write
mask, allowing us to write only a subset of channels to the tilebuffer. It's
more efficient to use that than to emit pointless tilebuffer loads.

Note that even without tilebuffer loads, non-opaque masks don't work with opaque
pass types.  Here, we handle this with a translucent pass type, which gets HSR
to do the right thing and is consistent with the pass type used previously.
However, it's a bit heavy handed -- Apple manages to use an opaque pass type
with masking but with some unknown HSR fields twiddled. IMO reverse-engineering
those details shouldn't block this because this gets us closer to optimal (just
not all the way there) and is strictly better than what we had before.

f603d8ce9e asahi: Clang-format the subtree
See 0afd691f29 ("panfrost: clang-format the tree") for why I'm doing this.
Asahi already mostly follows Mesa style so this doesn't do much. But this means
we can all stop thinking about formatting and trust the robot poets to do that
for us.

66a680a043 asahi: Add tilebuffer layout helpers
Laying out the tilebuffer is nontrivial and a task shared between GL and VK, so
add unit-tested helpers.
