Midgard has the ability to calculate addresses as part of the load/store
pipeline. We'd like to make use of this to avoid doing this work on the
ALU pipes. To do so, when emitting globals/SSBOs/shareds, we walk the
tree looking for address arithmetic to try to parse out something the
hardware can work with, letting the original instructions be DCE'd
ideally. This analysis is done at the NIR level to properly account for
some messy details of vectorization which we'd rather not poke at the
backend level. (Originally I wrote this as a MIR pass but I'm fairly
sure it was wrong.)

The swizzles are as-if they were 32-bit regardless of the bitness of the
operation, but the source sizes can and do change depending on the

When mixing 32/64-bit, we need to align the 32-bit registers to get the
required alignment. This isn't quite enough yet, though, since user
swizzles could bypass and will need to be lowered to 32-bit moves
(outstanding todo).

I'm working on moving the db410c CI from docker to LAVA, which means we
get to boot a custom kernel. To do that, we need to enable ARCH_QCOM in
the kernel, save the dtb around, and include abootimg in our container so
that we can generate combined kernel/dtb/ramdisk images for fastboot.
LAVA's fastboot support is unable to pack the overlay into an abootimg
image, just a cpio rootfs. We could flash the cpio rootfs after overlay
addition, but that takes 2 minutes to do, and causes wear on the devices.
Instead, we'll bring up the network at boot and use wget to fetch the
overlay. We'll want network support anyway, so that we can transfer the
failure xmls back to the gitlab job's artifacts at some point.
Since the msm GPU and realtek network firmware increase our payload by
3MB, add in firmware compression so that it doesn't waste as much RAM on
devices not using it.

The LLVM libraries were a significant fraction of the entire payload
(55M/250M uncompressed) into the initramfs of the test boards, but
LLVM is only used for the draw module used in select/feedback (which
isn't even tested in CI on ARM yet).
Assume that llvmpipe draw is safe enough for ARM given the coverage on
x86, and disable LLVM for these jobs.

This field controls the size of per-thread temporaries (somehow this is
separate from the regular stack for register spilling..), though I'm not
certain on the details. Regardless this value of 0x1e despite being used
in places by the blob seems wrong and is interfering with correct sizing
of the stack.
We don't use non-spilling scratchpad yet, so this is just here to fix
some details of spilling.

These two cases were flipped from the notes, leading to underestimates
of the padded vertex count, manifesting as visual corruption (random
geometry messed up). This issue was raised when noticing the corruption
went away when dramaticlaly oversizing max_index on an instanced indexed
draw, and then checking that padded_count >= vertex_count -- which
turned out *not* to be the case on certain inputs, a clear issue. Hence
looking into this routine...

For index bufer resources (not user index buffers), we're able to cache
results. In practice, the cache works pretty dang well. It's still
important that the min/max computation is efficient (since when the
cache misses it'll run at draw-time and we don't want jank), but this
can eliminate a lot of computations entirely.
We use a custom data structure for caching. Search is O(N) to the size
but sizes are capped so it's effectively O(1). Insertion is O(1) with
automatic oldest eviction, on the assumption that the oldest results are
the least likely to still be useful. We might also experiment with other
heuristics based on actual usage later.
