This reverts commit 382f6ccda8.
The spec requires that all color images created with the same tiling
(and a few other properties) support the same memoryTypeBits. So this
wasn't a valid change. It also wasn't necessary - we already have a
mechanism in anv_BindImageMemory2 for disabling compression if the BO
doesn't support it.
With this, XeHP passes the tests in
dEQP-VK.memory.requirements.*tiling_optimal

When an image configured for HIZ_CCS/HIZ_CCS_WT is bound to a BO lacking
implicit CCS, we disable any compression it may have had. Such images
are still compatible with ISL_AUX_USAGE_HIZ however. Fall back to that
aux usage to retain the performance benefit.

When an image is bound to a BO lacking implicit CCS, we disable any
compression it may have had. This is unnecessary in the cases where the
compression type doesn't depend on the BO having implicit CCS support.
Avoid this disabling for ISL_AUX_USAGE_MCS and ISL_AUX_USAGE_HIZ.

This raises our vertex input bindings limit from 28 to 31, and our
vertex input attribute limit from 28 to 29. We could theoretically
go higher, but it will take additional work.
The 3DSTATE_VERTEX_BUFFERS and 3DSTATE_VERTEX_ELEMENTS limits are 33
vertex buffers, and 34 vertex elements. But we need up to two vertex
elements for system values (FirstVertex, BaseVertex, BaseInstance,
DrawID), and we currently use two vertex bindings for those.
There is another hidden limit: our compiler backend only supports the
push model for VS inputs currently. 3DSTATE_VS only allows URB Read
Lengths between [0, 15], which is measured in pairs of inputs, which
means we can theoretically push no more than 32 vertex elements. This
is no artifical limit either, as a vec4 element takes up 4 registers
in the payload, and 32 * 4 = 128, the entire size of our register file.
Plus, the VS Thread payload needs at least g0 and g1 for other things,
so we can really only push 31.
We can theoretically support one additional binding, by combining our
two SGV bindings into a single upload. In order to support additional
vertex elements, we would need to add support to the backend compiler
for the pull model for VS inputs.

The Vulkan 1.3 spec says:
"The implementation-dependent limit bufferImageGranularity specifies
a page-like granularity at which linear and non-linear resources
must be placed in adjacent memory locations to avoid aliasing. Two
resources which do not satisfy this granularity requirement are said
to alias. bufferImageGranularity is specified in bytes, and must be
a power of two. Implementations which do not impose a granularity
restriction may report a bufferImageGranularity value of one.
Note: Despite its name, bufferImageGranularity is really a
granularity between "linear" and "non-linear" resources."
We set this limit to 64 bytes (a cacheline) at the dawn of time, without
any real rationale attached. There shouldn't be any restrictions here.
Our tile sizes are typically 4K, and tiled resource addresses are
aligned to the tile size, and the extent is also a multiple of the tile
sized. So if a linear resource occurs before a tiled one, there will
naturally be some space due to the alignment of the tiled resource's
starting address. If a linear resource occurs after a tiled one, the
tiled resource's ending address is already 4K aligned, which is already
guaranteeing that they won't share a cacheline.
So I think it should be fine to reduce this to 1. The other Vulkan
driver for our hardware seems to advertise 1 here as well.

Commit 38800b38 changed nir_opcodes.py, but that doesn't seem to have
triggered nir_opt_algebraic.py. The change in 75ef5991 depends on
opt_algebraic lowering 16-bit versions of slt, but if opt_algebraic is
not rebuilt, this may not happen. This resulted in some people seeing
assertion failures in, for example,
dEQP-VK.spirv_assembly.instruction.compute.float16.arithmetic_3.step,
due to the backend seeing nir_op_slt that it didn't know how to handle.
v2: Add nir_opcodes.py to nir_algebraic_py so that all the per-driver
algebraic passes pick up the dependency too. Rename it to
nir_algebraic_depends. Suggested by Emma.

If a secondary command buffer is used and the client provides a
framebuffer and that framebuffer has a stencil-only attchment, we would
try to get the aux usage for the depth component of that attachment and
crash. Check the aspects of the image before looking at aux usage.
This fixes at least the following SkQP tests on my Tigerlake:
- vk_circular-clips
- vk_filterfastbounds
- vk_innershapes_bw
- vk_lineclosepath

When I originally added vk_image_view, I was overly clever when it came
to the format field. I decided to make it only contain the bits of the
format contained in the selected aspects. However, this is confusing
(not generally a good thing) and it's also not always what you want.
The Vulkan 1.3.204 spec says:
"When using an image view of a depth/stencil image to populate a
descriptor set (e.g. for sampling in the shader, or for use as an
input attachment), the aspectMask must only include one bit, which
selects whether the image view is used for depth reads (i.e. using a
floating-point sampler or input attachment in the shader) or stencil
reads (i.e. using an unsigned integer sampler or input attachment in
the shader). When an image view of a depth/stencil image is used as
a depth/stencil framebuffer attachment, the aspectMask is ignored
and both depth and stencil image subresources are used."
So, while the restricted format makes sense for texturing, it doesn't
for when the image is being used as an attachment. What we probably
actually want is both versions of the format. We'll call the one given
by the VkImageViewCreateInfo vk_image_view::format and the restricted
one vk_image_view::view_format.
This is just the first commit which switches format to view_format so
the compiler will make sure we get them all. The next commit will
re-add vk_image_view::format but this time unmodified.

This (sort of) matches the behavior of nir_opt_algebraic. This ensures
that subnormal values are properly flushed to zero.
With the aid of "nir/search: Float sources of texture instructions are
float users" and "nir/search: Transitively apply is_only_used_as_float",
there would have been no shader-db regressions on Intel platforms.
However, those caused a significant increase in compile time. Since the
instruction regressions were so small, I just dropped those commits
rather than improve them.
